Answer:
6.75
Explanation:
Consider the ratio:
$4.50 : 6 apples
We need to multiply this ratio by a value such that the right side is 9 because there are 9 apples in array p. This value is 9/6 = 3/2.
$4.50 : 6 apples
× 3/2 × 3/2
$6.75 : 9 apples
So, the value of p, or 9 apples, is $6.75, which you will input as 6.75.
