Jessica decides to mix grades of gasoline in her truck. She puts in 8 gallons of regular and 8 gallons of premium for a total co
Mariulka [41]

Answer:

The price of the regular gasoline is $2.46, while the premium is $2.67.

Step-by-step explanation:

Let the price of regular gasoline be "x", while the price for the premium be "y", The sum of the amount of each type of gas multiplied by its cost should be equal to the total paid, therefore:

8*x + 8*y = 41.04

We also know that the premium gas costs 0.21 more than the regular one, therefore:

y = x + 0.21

We can apply the second expression on the first, in order to solve for "x".

8*x + 8*(x + 0.21) = 41.04\\8*x + 8*x + 1.68 = 41.04\\16*x = 41.04 - 1.68\\16*x = 39.36\\x = \frac{39.36}{16} = 2.46

y = 2.46 + 0.21 = 2.67

The price of the regular gasoline is $2.46, while the premium is $2.67.
