<h3>
Answer: 40 novels</h3>
================================================
Work Shown:
n = number of novels
(32 ebooks)/(n novels) = 4/5
32/n = 4/5
32*5 = n*4 ............ cross multiply
160 = 4n
4n = 160
n = 160/4 .............. dividing both sides by 4
n = 40
There are 40 novels.
The answer is a.
4 P 4 = 24
Subtract 76 on both sides:
2401 - 76 = 76 - 2x - 76
2325 = -2x
Divide both sides by -2:
-1162.5 = x
