I already have part a.

anonymous · Answer

Part b) (25*7.50)+(0.2*300)+40=187.5+60+40=187.5+100=287.5

anonymous · Answer

thank you! so for part c it the variables, coefficients, and constants would be the same if she got a $9 dollar raise right?

anonymous · Answer

The variables would stay the same, I think the constants would too, but the first coefficient wouldn't since instead of 7.50, it would be 9.

anonymous · Answer

the first coefficient will be a constant.
