The cost of a gallon of milk (m) is .50 more than 5 times the cost of a gallon of water (w). If a gallon of milk cost 3.75, what is the cost of a gallon of water?

We're given:
m = 5w + 0.50
m = $3.75

Set them equal to each other:
5w + 0.50 = 3.75

Typing this equation into our search engine, we get:
w = 0.65
