Question

The basketballs Noah packed had two different prices. Of the total number of basketballs sold, 60% had a price that was $21 more than the price of the remaining basketballs. The total amount of the store’s sales for all the basketballs was $8,967. What was the price for one of the more expensive basketballs?

Answer 1

Answer:

$(8967/n + 8.4)

Step-by-step explanation:

0.4nx + 0.6n(x+21) = 8967

nx + 12.6n = 8967

x = 8967/n - 12.6

x+21 = 8967/n + 8.4

Where n is the no. of balls

Example: if total balls were 300

n = 300

More expensive one would cost:

8967/300 + 8.4 = $38.29
