Ken has $18 to spend on two models of the solar system and supplies to paint them. The two models cost the same amount. His paint supplies cost $4.62. Which expression indicates how much he can spend on each model?
It is H because he has $18 minus the cost for paint supplies. He's left with $13.38, and he can't spend over that as that is all he has. So, it must be less than or equal to $13.38.
