Samuel invested money in his bank account. He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, r, of 0.15 per year. At the end of the period, he had interest, I, of $105 in his account. Use the simple interest formula I = Prt, to solve for the time, t, in months that it took to earn this amount.
Hey there! I'm happy to help!
Let's see what we have for each variable.
I = 105
P = 100
r = 0.15
Now, let's plug it in and solve for our t (time)
105=100(0.15)(t)
Swap sides so t is on the left.
100(0.15)(t)=105
Divide both sides by 100.
0.15t=1.05
Divide both sides by 0.15
t=700
So, we see that it takes 700 months to earn this amount.
Have a wonderful day and keep on learning! :D
The number of months that it took to earn this amount will be 84 months.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
I = (PRT)/100
Where P is the principal, R is the rate of interest in percentage, and T is the time.
Samuel invested money in his bank account.
He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, R, of 0.15 per year.
At the end of the period, he had interest, I, of $105 in his account.
105 = 100 x 0.15 x t
t = 1.05 / 0.15
t = 7 years
The number of months that it took to earn this amount will be
⇒ 7 x 12
⇒ 84 months
The number of months that it took to earn this amount will be 84 months.

Rowena sells a dress for $42.60 after making a profit of 20% on the cost price.
Calculate the cost price.
20
$ ...................................................
Answer:
$35.50
Step-by-step explanation:
With a 20% profit then $42.60 represents 120%
We require to find the cost price represented by 100%
Divide the amount by 120 to find 1% then multiply by 100, that is
cost price = [tex]\frac{46.60}{120}[/tex] × 100 = $35.50

If R is the midpoint of QS, find QS. (2x + 16) and (5x - 17) Brainliest to correct answers. Please no spamming or random answers this is due tmrw thx.
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS , then
RS = QR , that is
5x - 17 = 2x + 16 ( subtract 2x from both sides )
3x - 17 = 16 ( add 17 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11
Then
QS = QR + RS
= 2x + 16 + 5x - 17
= 7x - 1
= 7(11) - 1
= 77 - 1
= 76

On an airplane, the passengers may have chicken, vegetable or tomato soup
Half of the passengers choose chicken soup
A third of the passengers choose tomato soup.
(a) What fraction of the passengers choose vegetable soup?
There are 240 passengers on the airplane.
(b) How many passengers choose vegetable soup?
Answer:
1/6 and 40
Step-by-step explanation:
for 1/6 you can get the answer by getting 1/2 chicken = 3/6 then 1/3 tomato soup = 2/6 and you have 1/6 left which will be the answer.
For the number of people, 1/6 is equal to 40 because 240 divided by 6 equals 40

1. Dividing thirty by one more than an integer is the same as dividing twenty-four by one less
than the integer. Find the integer algebraically using rational expressions.
Answer:
9
Step-by-step explanation:
Let the integer be n
According to the text
30 / (n + 1) = 24 / (n-1)
Cross multiply we have
30 (n -1) = 24 (n + 1)
30 n - 30 = 24 n +24
30n -24n = 30 + 24
6n = 54
n = 9.
So the integer is 9.

The three angles
6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘
add up to 360∘360∘, as per the question.
6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘
⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘
⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘
⟹2x+3y+z=90∘⟹2x+3y+z=90∘

The selling price of a refrigerator, is $638.00. If the markup is 10% of the dealer's cost, what is the dealer's cost of the refrigerator?
25% markup = original + 25% = 125% of original = 1.25 x original
Selling price = 1.25 x dealer price
Answer = 521.25/1.25=$417
The dealers price would be 100% they sell it for 10% more so it is sold at 110 % of what the dealer pays.
Divide the selling price by 110% to get the dealers cost.
638 / 110% = 638 / 1.1 = 580
The dealers cost is $580
The average length of time that three computers operate on a given day is 960 minutes. None of the computers operate for less than 930 minutes. What is the greatest possible length of time any one of the computers operates
The greatest possible length of time will be "1020 min".
Given:
The average length of time,
= 960
For all 3 computers,
The minimum length of time,
= 930
Let,
The length of time of 2 computers will be "930".The 3rd one be "930+x".Now,
→ [tex]\frac{930+930+930+x}{3} = 960[/tex]
→ [tex]\frac{930+930+930}{3} +\frac{x}{3} =960[/tex]
→ [tex]\frac{3\times 930}{3} +\frac{x}{3} =960[/tex]
→ [tex]930+\frac{x}{3}=960[/tex]
→ [tex]\frac{x}{3} = 960-930[/tex]
→ [tex]x = 30\times 3[/tex]
→ [tex]x = 90[/tex]
hence,
The greatest possible length of time will be:
= [tex]930+x[/tex]
= [tex]930+90[/tex]
= [tex]1020 \ min[/tex]
