She will spend $74.25 on gas.
Step-by-step explanation:
Given,
27 miles = 1 gallon
1 mile = [tex]\frac{1}{27}\ mile[/tex]
Distance to cover = 892 miles
We will multiply this number with gallons of gas used for 1 mile.
892 miles = [tex]\frac{1}{27}*892[/tex]
892 miles = 33.04 gallons of gas
Rounding off to nearest whole number;
892 miles = 33 gallons
Cost of one gallon of gas = $2.25
Cost of 33 gallons = 2.25*33 = $74.25
She will spend $74.25 on gas.
