The question is as follows:
High gloss paint costs $15 more per gallon than Flat finish paint. If the cost of one can of each is 250% of the cost of a gallon of Flat finish paint, how much is the cost of a gallon of Flat finish paint?
The eqns i was able to come up with:
H= high gloss paint cost
F= finish gloss paint cost
H=15+F
250/100F
But there is also an eqn in the soln at the back: F+F+15=250/100F
I dont understand how they found this last relationship? I would appreciate some feedback. thanks
