Answer:

The difference in the cost of filling your tank between the two grades of gasoline is $2.28.

Step-by-step explanation:

Given : Our car has a 15-gallon gas tank. A lower grade of gasoline costs $2.96 per gallon. The premium grade gasoline costs $3.15 per gallon. There are three gallons left in your gas tank.

To find : What is the difference in the cost of filling your tank between the two grades of gasoline?

Solution :

The gas tank is of 15 gallons

There are three gallons left in the gas tank.

The tank has to be filled with 15 - 3 = 12 gallons

A lower grade of gasoline costs $2.96 per gallon.

So, the cost of filling the tank with the lower grade gasoline is

C_1=12\times 2.96

C_1=\$35.52

A upper grade of gasoline costs $3.15 per gallon.

So, the cost of filling the tank with the lower grade gasoline is

C_2=12\times 3.15

C_2=\$37.8

The difference in the cost of filling your tank between the two grades is

C= $37.80 - $35.52

C= $2.28

Therefore, the difference in the cost of filling your tank between the two grades of gasoline is $2.28.

The Garcia family and the Johnson family each used their sprinklers last summer. The Garcia family's sprinkler was used for 20 h
VladimirAG [237]

W is the time Woody family used sprinkler.

C is the time Carter family used sprinkler.

Time used total: 50 hours.

W+C = 50                                 (1)

Total water used is 1900 L.

Woody family used: 40W;

Carter family used 35C.

Equation showing how much water both families used:

40W + 35 C =1900.                   (2)

We have a system with two equations and two variables. We can use substitution method to solve the system. From equation (1) we express W:

W=50 - C.                                              (1a)

We substitute the variable in equation (2):

40(50 - C) +35C =1900.

We open the parenthesis

2000 -40C +35C =1900,

We combine like terms

2000 -5C =1900,

We subtract 2000 from both sides of the equation

-5C = 1900 - 2000,

We simplify

-5C = -100,

We divide by -5

C = 20.

We substitute the values of C in the equation (1a) and find the value of W:

W = 50 - C,

W = 50 -20 =30.

The Woody family used water for 30 hours and the Carter family used water for 20 hours.

We check our work to be sure we did not make any mistakes:

Total water used:

40 x 30 + 35 x 20 = 1200 + 700 = 1900 L.
