Question

Someone please help me with #15

Answer 1

Answer:

b. A year and a half

Step-by-step explanation:

First, we can find the total cost

$1512+263=1775$

Next, we can divide by 50 in order to find out how many months it will take for the panel to pay for itself.

$\frac{1775}{50} =35.5$ months

This is very close to 36 months, which is A year and a half.
