A space heater costing $235 offers an extended warranty for 15% of the purchase price. If the local repair shop will fix a space heater for $12, how many times must the space heater need repairs for the warranty to be worth the cost? a. one b. two c. three d. four
The answer is C, this is because 15% of 235 is 35.25. If the repair shop fixes the heater for $12, 12x3=36, which means that to get your money back, you would need to have it repaired 3 times.
