Answer:
b. A year and a half
Step-by-step explanation:
First, we can find the total cost
[tex]1512+263=1775[/tex]
Next, we can divide by 50 in order to find out how many months it will take for the panel to pay for itself.
[tex]\frac{1775}{50} =35.5[/tex] months
This is very close to 36 months, which is A year and a half.
