Question

Daisy works at an ice-cream parlor. She is paid $10 per hour for the first 8 hours she works in a day. For every extra hour she works, she is paid 1.5 times her hourly wage. If Daisy works for x hours in a day, and x is greater than 8, the expression giving her net earnings for the day is . If Daisy works 13 hours, she will be paid .

Answer 1

Total net earnings =
`80+15(x-8)`

If Daisy works 13 hours, she will be paid $155.

Explanation:

Let Daisy works for x hours a day

She is paid $10 per hour for the first 8 hours she works in a day.

So, pay for the first 8 hours =
`10*8=80` dollars

For every extra hour she works, she is paid 1.5 times her hourly wage.

The number of hours worked over 8 hours is given by =
`x-8`

So, pay for the hours worked over 8 hours =
`15(x-8)` dollars

Total net earnings =
`80+15(x-8)`

And when x = 13

The pay is :
`80+15(13-8)`

=
`80+15(5)`

=
`80+75` = 155 dollars

Hence, if Daisy works 13 hours, she will be paid $155.
