Homework Help: math 115

You can use functions to figure how much money you earn in a day..if you work "x" hours in a day and you make $"y" in a day.
So let's say that you work 5 hours in a day and you make $9 an hour
y=5x+9
9x5=40 would this be the right way of working this problem out

no, just y = 9 x
y = 9 * 5
y = 45 (not 40 by the way)
