No Explanation

a) 45h

Explanation:

all you need to do to find out how much he earns for a certain amount of time is to multiply the rate by the number of hours he works. since our rate is 45 and since h represents the number of hours he works, you would just need to plug in a number for h to be able to solve, since 45h or 45(h) is the same thing as 45 times h.
