To find the amount that each of the 4 friends paid for the peaches, you should first calculate the total cost of the peaches, then divide by the numer of friends (4).
First, let's calculate the total cost of the peaches.
18.4 pounds × $1.75/pound = $32.20
Now, divide by the number of people who were contributing to the cost of the peaches (there are 4) -
$32.20 ÷ 4 = $8.05
The correct answer is $8.05.
