By installing a $120 thermostat that reduces the temperature setting at night, a family hopes to cut its annual bill for heating oil by 8 percent, and thereby recover the cost of the thermostat in fuel savings after 2 years. What was the family's annual fuel bill before installing the thermostat?
since it would only take 2 years to recover the amount with 8percent per year, then you can say that let x be the bill per year 8% of x times 2 = 120 0.08x (2) = 120 0.16x =120 x=$750 therefore you can say that the annual fuel bill before installing the thermostat is $750
