GIVEN THE FOLLOWING:
Mario's car rate consumption. R = 24.5mile/gallon
Distance covered each day, D = 32.3 miles
Cost of gas $2.89/gallon
REQUIRED: (a) To calculate how much he spends on gas each week.
We proceed as follow:
Mario uses 1 gallon of gas for every 24.5 miles.
For 32.3 miles, he will use
Now, a gallon of gas costs $2.89
$3.81 is how much he spends each workday.
There are 5 working days in a week.
Therefore, for a week, he spends:
therefore, for each work week, he spends $19.05 on gas.
(B) To calculate how many miles he can drive with $15.00 worth of gas
We proceed thus:
A gallon of gas costs $2.89.
$15.00 will amount to:
$15.00/$2.89 = 5.19 gallons
Recall that Mario uses 1 gallon of gas for every 24.5 miles.
Therefore, 5.19 gallons will be used for:
≈ 127 miles
Therefore, with gas worth $15.00, Mario will cover a distance of 127 miles
