Daisy works at an ice-cream parlor. she is paid $10 per hour for the first 8 hours. she works for x hours in a day and x is greater than 8, the expression giving her net earnings for the day is
a. x(80+1.5)
b. (x-8)1.5
c. 80+15 (x-8)
d. (8)(15)(x-8)

Some information is missing. The logical assumption is that you forgot to write that the rate for the hours worked over 8 hours is 50% more than the regular rate or, what is the same 1.5 times.

With that this is the solution step by step:

1) Number of  hours worked: x

2) Rate for the first 8 hours: $10 per hour

2) Pay for the first 8 hours = $10 * 8 = $80

3) Number of hours worked over 8 hours = x - 8

4) Rate for the hours worked over 8: 1.5 times $10 per hour = $15 per hour

5) Pay for the hours worked over 8 = $15 (x - 8) = 15 (x - 8)

6) Total pay = 80 + 15 (x - 8)

That is the option C.

option C. 80 + 15(x - 8)
