Question
The expression 7h + 1.50d can be used to find the total earnings after h hours and d deliveries have been made. Sally make after working 10 hours and making 3 deliveries total is ?
- $74.50
- $36
- $30
- $70
Hint:
Substitute h with the value 10 and d with the value 3
The correct answer is: $74.50
The expression 7h + 1.50d
Substitute h= 10, d = 3
=7(10) +1.50(3)
=70+ 4.50
=$74.50
