Write an expression that represents the amount Tina is paid each day given the number of cars (c) she washes.

37+1.50(c)= ?

Write an expression that represents the amount Jim is paid each day given the number of cars (c) he washes.

40+1.00(c)= ?

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?

can you help me with this part.

Are those expressions correct above?

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
