Heating plant

Workers dump imported coke at the heating plant. They used half of the amount on the first day. On the second day, three-quarters of the rest and on the third day left 120 tons. How much coke did they dump at the heating plant?

Correct answer:

x =  960 t

Step-by-step explanation:


x-1/2 x - 3/4 · (x-1/2 x) = 120

x-1/2·x - 3/4 · (x-1/2·x) = 120

0.5x = 480


x = 480/0.5 = 960

x = 960
