On Monday, Tina and Jim washed the same number of cars and earned the same amount of money. How many cars did they each wash on Monday?

the expressions are correct. If c is the same for both, and the earnings are also the same, then we have

37+1.5c = 40 + 1.0c
.5c = 3
c = 6

check:
37+1.5(6) = 37+9 = 46
40+1(6) = 40+6 = 46
Now I understand....thank you so much!
