Question

Lydia earns $18 per hour and a $125 bonus for working on a weekend

Which equation represents the amount of money Lydia has earned this
weekend, y, in relation to the number of hours she has worked, x?
A y = 125 - 18x
By = 125 + 18x
C y =
125x-18
D
y = 125x + 18

Answer 1

Option B

Explanation:

y = 125 + 18x

In words, Lydia earns $125 plus $18/hr times however many hours she works (which we are calling x).

Option A doesn't make sense; you wouldn't subtract from her $125 bonus for the hours she worked times her $18/hr wage.

Option C doesn't make sense. The $125 is a fixed amount and you don't multiply that bonus times the number of hours that she has worked.

Option D doesn't make sense for the same reason as above.
