W = 120 + 5(h - 30).
So, if he works 35 hours, he will earn:
120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.
If he works 42 hours, he will earn:
120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.
Answer:
3
Step-by-step explanation:
3.5*4.5=15.75 ft^2
15.75/5.25=3 bags
The answer is 225 dollars because you divide 150/20=7.5 then multiply 7.5(30) and you get 225
I feel it should be 30 because x represents the number of lessons, and 30 is multiplied by that.
