Your total cost is $ 1348.20
Step-by-step explanation
Fees of the Aerobics is $21 per month for 18 months. So the total fees in 18 months = $21 × 18 = $378
Number of visits is 11 per month, so the total number of visits in 18 months = 11 × 18 = 198
Transportation cost is $4.90 per visit, so the total transportation cost for 198 visits = $4.90 × 198 = $ 970.20
So, the total cost = (Total fees) + (Total transportation cost) = $ 378 + $ 970.20 = $ 1348.20
