Problema Solution
In 1996 hydroelectric power production hit an all-time hight of 376 billion kilowatt-hours. This is 6 billion kiloatt-hours more than four times the 1950 production level. Find the amount of hydroelectric power produced in 1950
Answer provided by our tutors
let the production level in 1950 be p
376 = 6 + 4p solve for p
370 = 4p
92.5 = p
so the amount of power produced in 1950 was 92.5 billion killowatt-hours
