Answer:

2190 ; 2560 ;

$778.2

Step-by-step explanation:

Total worth of gasoline sold = 16003.50

Cost of regular = 3.30

Cost of premium = 3.45

Let :

premium Gallon sold = x

Regular gallon sold = 370 + x

Hence, mathematically;

(3.45*x) + (3.30 * (x + 370)) = 16003.50

3.45x + 3.30x + 1221 = 16003.50

6.75x = 16003.50 - 1221

6.75x = 14782.5

x = 14782.5 / 6.75

x = 2190

Premium Gallon sold = 2190 gallons

Regular gallon sold = 2190 + 370 = 2560 gallons

Profit per regular gallon sold = $0.15

Progit per premium Gallon sold = $0.18

Total profit = (2190 * 0.18) + (2560 * 0.15) = $778.2
