Question

The water level in a reservoir is now 52 meters. If this was a 23% increase, what was the initial depth?

Answer 1

40.04

Explanation:

It was at 40.04 before the 23% increase. To find 23 % of 52 set it up as a inequality.

x/52 = 23/100

Cross multiply

52 * 23 = 1,196 100 * x =100x

Now solve for x.

100x /100 = 1,196/100 x = 11.96

Subtract answer from 52 to get answer

52 - 11.96 = 40.04
