Question

Janet pays $350 annually for her gym membership plus $8 each time she takes a pilates class. Last year, Janet took 20 pilates classes. What percent of her total gym cost was represented by her pilates classes? Round the answer to the nearest tenth of a percent.

Answer 1

To answer the question above, multiply the number of pilates classes Janet took last year with $8. Since she took 20 classes, this amounted to $160. Her total gym cost for last year was the $350 annual payment plus the $160 from pilate classes. These totalled to $510. $160 is approximately 31.4% of $510. Thus, the answer is 31.4%.
