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
