4 0

Answer:

90 balls

Step-by-step explanation:

Set up proportion

36/x = 40/100

Cross multiply: 40x=3600

Solve for x

x=90

To check work:

40 percent of 90 would be 36

90(0.4)=36

. Jumbo bought 5 books, each with a whole-number price.
Trava [24]

Mean is average. Multiply total books by the mean to find the total cost:

5x 10 = $50 total.

Subtract the highest and lowest prices to find the total of the remaining 3 books.

50 - 15-6 = 29

The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:

29-8 =21

Now you need a price lower than the median but higher than the lowest cost so that has to be 7

Subtract 7 from 21 to get the cost of the last book 21-7 = 14

The price of the remaining books is $7 and $14
