Based on the charged amount, Lupita drove 8.76 miles.
Let us assume the number of miles rode bh Lupita be x. Forming the equation now -
Total charge = flat rate + cost per mile × number of miles
Keep the values in above mentioned equation to find the value of x
40.03 = 6.75 + 3.20×x
Rewriting the equation with respect to x
3.20x = 40.03 - 6.75
3.20x = 33.28
Shifting 3.20 to Right Hand Side of the equation
x = 33.28 ÷ 3.20
Performing division on Right Hand Side of the equation
x = 8.76 miles
Thus, Lupita drove 8.76 miles.
