Jason puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gallon Jason purchased?

a) 30g = 2.5

b) 30/g = 2.5

c) 30 + g = 2.5

d) 30 = 2.5 + g

So, this is a rate problem, so the forumla we would get is

2.5g=30

(Note this is not one of the choices), so if we look, there is an equivelent equation.

If we divide both sides by g we get

2.5=30/g

B is the correct answer
