Question #8023

A tank was 1/2 full of water.after 420 gaallons had been taken out it was 1/8 full.Find the capacity of the tank.

Expert's answer

Let's denote capacity of tank as x. So we have:

1/2*x-420=1/8*x

(1/2-1/8)x=420

(4/8-1/8)x=420

3/8*x=420

x=420*8/3=340*8=1120 gallons

1/2*x-420=1/8*x

(1/2-1/8)x=420

(4/8-1/8)x=420

3/8*x=420

x=420*8/3=340*8=1120 gallons
