Jake paid $40.50 per solar panel for eight panels and an additional installation fee for a total of $338.50. Jen paid $42.99 per panel for eight panels and an additional installation fee for a total of $354.42. Find the difference between the installation fees Jake and Jen paid.

Answer: $4.00

Step-by-step explanation:

$40.50 * 8 = $324.00

$338.50 - $324.00 = $14.50

Jake's installation fee is $14.50

$42.99 * 8 = $343.92

$354.42 - $343.92 = $10.50

Jen's installation fee is $10.50

To find the difference between the two fees, you subtract the larger fee by the smaller fee.

$14.50 - $10.50 = $4.00
