Respuesta :

Answer: $4.20

Explanation: First, we need to know how much was spent on apples and peaches.

The equation for the amount spent on apples is $1.32/1 lbs=$x=(2 3/4 lbs), where 2 3/4 * 1.32=$3.63

As for peaches, we have $1.20/1 lb=$x/(1.5 lbs), where 1.5 * 1.20=$1.80

Finally, $9.63-(3.63+1.80)=$4.20
