Question

You need to buy fruit for a party (cool party, right?) In a supermarket, apples cost $1.00 each (x), and grapefruits cost $2 each (y). If you want to spend exactly $16 at the supermarket, write an equation in standard form modeling this situation.

Answer 1

The apples are x and cost $1, and the grapefruits are y and cost $2.

So, 1x and 2y

These together must equal $16

1x + 2y = 16

Hope this helped :)
