You plan to join aerobics now. here are the details of your costs: $21 per month for 18 months, number of visits is 11 per month, transportation is $4.90 per visit. what are your total costs?

Your total cost is $ 1348.20

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                                  

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

i think that you should ask google for the answer to that problem because if we don't know it google does
