Nov 6 at 8:13am Instructions Question 1 1 pts Which equation matches the situation below? The water level in a reservoir is now 52 meters. If this was a 23% increase, what was the initial depth? O 0.23x=52 O 1.77x=52

Answer 1

Let the initial depth be x

If there is an increase, the difference

= 52 - x meters

In percentage

(52 - x)/x = 0.23

52 - x = 0.23x

52 = 1.23x

1.23x = 52

Divide both sides by 1.23

x = 52/1.23

x = 42.28 meters
