Ответ:
138.27 gallons
Step-by-step explanation:
Total cost = snacks + gallons * cost per gallon
387 = 35.80 + g*2.54
Subtract 35.80 from each side
387-35.80 = 35.80-38.50 + g*2.54
351.20= + g*2.54
Divide by 3.54 on each side
351.20/2.54 = 2.54g/2.54
138.2677165 = g
Rounding to the nearest hundredth
138.27 gallons
