Eric sells model cars from a booth at a local flea market. He purchases each model car from a distributor for $14 and the flea market charges him a booth fee of $30. Eric sells each model car for $20. How many cars will Eric have to sell to break even?
Answer: 5 cars
Step-by-step explanation:
Breakeven point = Fixed Cost/ Contribution margin
Fixed cost is $30 which is the flea market booth charge
Contribution margin is sales price less variable cost.
The Variable Cost is the amount he is charged by the distributor of $14.
Contribution Margin = 20 - 14
= $6
Breakeven point = 30/6
= 5 cars
Find the area of a circle with diameter 10 cm . Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer. Whatts the answer?
Answer:
Area of circle = 31.4 cm²
Step-by-step explanation:
Given the following data;
Diameter, d = 10 cm
π = 3.14
Area of a circle is given by the formula;
πd
Substituting into the equation, we have;
Area of circle = 3.14 * 10
Area of circle = 31.4 cm²
It costs $3 for children and $7 for adults to attend a school basketball game. If 5000 people attended the game and the total takings at the door was $25000, determine the number of children and the number of adults that attended the game, using simultaneous elimination.
Answer:
2500 children and 2500 adults
The number of children is 2500 and the number of adults that attended the game is also 2500.
System of equations:Let us consider that, number of children be x and number of adults be y that attend game.
Since, total 5000 people attend the game.
[tex]x+y=5000\\\\x=5000-y..........(1)[/tex]
It costs $3 for children and $7 for adults and the total takings at the door was $25000
[tex]3x+7y=25000 .............(2)[/tex]
Substitute value of x from equation 1 into equation 2.
[tex]3(5000-y)+7y=25000\\\\15000-3y+7y=25000\\\\4y=10000\\\\y=10000/4=2500[/tex]
So that, [tex]x=5000-2500=2500[/tex]
Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.

What are the explicit equation and domain for an arithmetic
sequence with a first term of 5 and a second term of 3?
Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: [tex]a_1=5[/tex]
Second term: [tex]a_2=3[/tex]
Common difference is
[tex]d=a_2-a_1[/tex]
[tex]d=3-5[/tex]
[tex]d=-2[/tex]
Now, the explicit formula for an arithmetic sequence is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
Putting a=5 and d=-2, we get
[tex]a_n=5+(n-1)(-2)[/tex]
It can also be written as
[tex]a_n=5-2n+2[/tex]
[tex]a_n=7-2n[/tex]
Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is [tex]a_n=5+(n-1)(-2)[/tex] or [tex]a_n=7-2n[/tex] and domain is all interest greater than or equal to 1.

A set of floor speakers costs $466. If the extended warranty on the speakers costs 32% of the price of the speakers, how much does the extended warranty cost
Answer: 149.12
Step-by-step explanation:
to find out the extended warranty we do,
466*(32/100)=149.12
The extended warranty cost is $149.12.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a set of floor speakers costs $466.
If the extended warranty on the speakers costs 32% of the price of the speakers.
Now, extended price =32% of 466
32/100 ×466
= 0.32×466
= $149.12
Therefore, the extended warranty cost is $149.12.

4. Find the value of the real number y such that
(3+2i)(1 + iy)
is :
(a) real
(b) imaginary
Step-by-step explanation:
(3 + 2i)(1 + iy)
= 3 + (3y + 2)i - 2y (because i² = -1)
For this to be real, (3y + 2) = 0. => y = -2/3
For this to be imaginary, y can be any real or complex number (except -2/3)

True or False? A triangle can have side lengths of 3, 3 , and 6
Answer:
No
Step-by-step explanation:
We can check with the Pythagorean Theorem.
a^2 + b^2 = c^2
a and b are always the smaller sides, the legs
c is the longer side, the hypotenuse
3^2 + 3^2 > 6^2
9 + 9 > 36
18 < 36
18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.

A financial institution offers a "double-your-money" savings account in which you will have $2 in 11 years for every dollar you invest today. What annual interest rate does this account offer? Please specify your answer in decimal terms and round your answer to the nearest thousandth (e.G., enter 12.3 percent as 0.123).

Generally we make use of this formula
[tex]F=P(1+r/100)^t[/tex]
where
[tex]f=Future value[/tex]
[tex]P= present value[/tex]
[tex]r=Rate[/tex]
[tex]t=time[/tex]
Mathematically solving for the rate
[tex]2=1(1+r/100)^1^1[/tex]
[tex](2)^1^/^1^1=(1+r/100)[/tex]
[tex](1+r/100=1.0650[/tex]
[tex]r=(1.0650-1) *100[/tex]
[tex]r=0.07[/tex]
Generally this shows that the account give an annual rate of 0.07
