Answer:
75+15*h
Step-by-step explanation:
A: we have $75, $15, and h (which is equal to hour spent). We have a keyword which is plus. So we add the 75+15, since we do not know the amount of hours he/she is doing then we put that as h. per is another keyword for multiplication. so we end up with 75+15*h.
B: for this we just need to put 2.5 in as h and we get the answer for this expression. so 75+15*2.5= 112.5
