Pitt's Pit Stop sold $15,733.50 worth of gasoline yesterday. Regular sold for $3.30 a gallon and premium sold for $3.45 a gallon. If the station sold 370 more gallons of regular than premium, answer the following questions.
How many gallons of each type of gasoline were sold?

in this question you need to make two equations one for total price and the other for total gallons. assume R is for gallons of regular gasoline and P is for gallons of premium gasoline sold.

[tex]3.3R +3.45P=15733.5[/tex]

[tex]P = R-370[/tex]

then substitute one of them at the other:

[tex]3.3R +3.45(R-370)=15733.5[/tex]

by solving the equation R = 2520

substitute R in equation P = R-370:

P = 2520-370 = 2150
