Answer:
$12.75
Explanation:
We can represent the relation of pies to dollars with the ratio:
pies : price
4/3 : $17
We are solving for how much 1 pie costs. To do this, we can multiply both sides of the ratio by 3/4 (the reciprocal of 4/3):
pies : price
4/3 : $17
× 3/4 × 3/4
1 : $12.75
So, 1 pie costs $12.75.
