if a shop owner purchased 20 pairs pf gloves at $12 each and some hats for $25 each, how many hats did he buy if he spent a total of $490

Answer:

$544.61

Step-by-step explanation:

Edmentum

In 4 years, Emma will owe about $544.61 to the credit card company.

The model for Emma's debt in 4 years is given as:

FV = P(1+r/n)^nt,

where:

P = principal ($300)

r = the interest rate (15%)

t = the time in years (4 years)

n = the number of times the interest is compounded per year (12)

However, we can solve the problem with an online financial calculator as follows:

N (# of periods) = 48 (4 x 12 months)

I/Y (Interest per year) = 15%

PV (Present Value) = $300

PMT (Periodic Payment) = $0

P/Y (# of periods per year) = 12

C/Y (# of times interest compound per year) = 12

Results:

FV = $544.61

Total Interest = $244.61

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card:

Thus, in 4 years, Emma will owe $544.61 to the credit card company.

Answer:

Step-by-step explanation:

Mean = Sum of data ÷ number of data set

         [tex]=\dfrac{9+3+15+7+2+4+3}{7}\\\\=\dfrac{43}{7}\\\\= 6.14\\\\= 6.1[/tex]

Median:

Arrange the data in ascending order:

2 , 3 , 3 , 4 , 7 , 9 , 15

Middle term is the median of the data set

Median  = 4th term = 4

Mode:

Mode is the data whose is frequency is more.

So, mode = 3

Range = Maximum - minimum

           = 15 - 2

           = 13

Answer:

mean = 10.818181...

median = 10

mode = 5

Step-by-step explanation:

first put the numbers in order, smallest to largest

5 5 6 8 9 10 11 13 15 18 19

mean = 5+5+6+8+9+10+11+13+15+18+19 = 119 119÷11= 10.818181818... (round it)

median = 10

mode = 5

The original price of the novel is $25.

The summary are:

So, the original price will be computed as follows:

= $22.50 / (1 - 10%)

= $22.50 / 0.90

= $25

Therefore, the original price of the novel is $25.

22/5

Explanation-

First, multiply 4x5, Then you get the product 20. With that 20, add with 2, so, 20+2=22. Now, place denominator as it is, then write 22 as numerator. So you get the answer as 22/5.

Working-

4×5=20

→ 20+2=22

→ 22

→ 22/5

Step-by-step explanation:

Answer:

Dimensions are 3cm and 10cm.

Step-by-step explanation:

We can make two equations for this problem.

ab = 30

2a + 2b = 26

Isolate a in the first equation.

a = 30/b

Plug that into the second equation.

2(30/b) + 2b = 26

2b^2 + 60 = 26b

2b^2 - 26b + 60 = 0

2(b - 3)(b - 10) = 0

b - 3 = 0 and b - 10 = 0

b = 3, 10

Plug these values into the first equation.

a3 = 30

a = 10

a10 = 30

a = 3
