Question

You sold a combined total of 25 of item A and item B. You made $88.

Item A: 3$
Item B: 4$
How much of each item did you sell?

Answer 1

x = 25 - y = 2

Explanation:

Let x represent the number of item A that you sold.

Let y represent the number of item B that you sold.

The total number of item A and item B sold is 25. This means that

x + y = 25

The cost of item A is $3, the cost of item B is $4 and if the total amount of money made is $88, this implies

3(x) + 4(y) = 88 (Substitute x = 25 - y)

→ 3(13 - y) + 4y = 88

→ 39 - 3y + 4y = 88

→ 39 + y = 16

→ y = 23

If y = 23, then x = 25 - y = 2
