Sagot :

Answer:

  • $48.88 required to fill the gas tank if it is already 38% full.
  • $72.46 is spends on that trip.

Step-by-step explanation:

Given that

  • A gallon of gasoline costs $2.96.
  • Gas tank capacity of the given car = 25 gallon
  • That car can travelled 28.8 miles on each gallon of gasoline.

To find

  • The cost of filling your gas tank if it is already 38 % full.
  • How much money spend on gasoline on the trip of 705 miles.

So according the question

We have

  • 1 gallon of gasoline =  $2.96.
  • Gas tank capacity = 25 gallon.
  • 28.8 miles travelled on each gallon of gasoline.

Now, for finding

a.) The cost of filling your gas tank if it is already 38 % full.

      38 % of 25 gallon = 9.5 gallon

      the unfilled part of the tank  = 25-9.5 = 15.5 gallon

      So the tank can filled 15.5 gallon of gasoline more now.

      The cost of 15.5 gallon of gasoline

                                   = 15.5 × cost of 1 gallon of gasoline

                                   = 15.5 × 2.96

                                   = $45.88

  • $48.88 required to fill the gas tank if it is already 38% full.

b.) How much money spend on gasoline on the trip of 705 miles.

    ∵ Car can travelled in 1 gallon of gasoline = 28.8 miles.

    ∴ Gasoline required to travel 705 miles = [tex]\frac{705}{28.8}[/tex]

                                                                        = 24.48 gallon.

      The cost of 24.48 gallon of gasoline

                                   = 24.48 × cost of 1 gallon of gasoline

                                   = 24.48 × 2.96

                                   = $72.46    

  • $72.46 is spends on that trip.
