Crystals fitness center offers yoga classes for $12 per class and sells yoga mats for 19.95. Dana's fitness center offers yoga classes for $13 per class and sells yoga mats for $9.95. After how many yoga classes will the cost be the same?

12x+19.95=13x+9.95

19.95=x+9.95

10=x

So after 10 classes the cost will be the same

12(10)+19.95=120+19.95= $139.95

13(10)=9.95=130+9.95= $139.95

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
