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:

x21x43 (x21x)=120  x1/2 x3/4 (x1/2 x)=120  0.5x=480  x=0.5480=960  x=960=960 t
