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 x(80 + 1.5)(x - 8)1.5 80 + 15(x - 8)(8)(15)(x - 8). If Daisy works 13 hours, she will be paid $1,506$600$475$155.

Answer 1

80+15(x-8), $155

Explanation:

Answer 2

Equation =
`80+15(x-8)`

Net earnings is $155.

Explanation:

Let the number of hours Daisy works = x

It is given that, she is paid $10 for the first 8 hours. That is, she is paid 10×8 = $80 in total.

Also, for the next hours she works, she is paid 1.5 times her hourly wage.

That is she is paid 1.5×10 = $15 for every next hour she works.

As, she works for 'x' hours, where x is greater than 8.

The equation representing the net earnings of Daisy =
`80+15(x-8)` in dollars.

So, when she works for 13 hours i.e. x= 13, her net earnings is,

Net earning = 80+15× (13-8) = 80 + 15 × 5 = 80 + 75 = $155

Thus, her net earnings after 13 hours is $155.
