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 [tex]\frac{32.3}{24.5} ~gallons~ of gas=\frac{325}{245} ~gallons[/tex]

Now, a gallon of gas costs $2.89

[tex]\frac{325}{245}~gallons~will~cost =?[/tex]

[tex]\frac{325}{245} ~*2.89=3.81[/tex]

$3.81 is how much he spends each workday.

There are 5 working days in a week.

Therefore, for a week, he spends:

[tex]3.81~*~5~=19.05[/tex]

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:

[tex]5.19~*24.5=127.155 ~miles[/tex]

≈ 127 miles

Therefore, with gas worth $15.00, Mario will cover a distance of 127 miles
