The cost to fill a car's tank with gas and get a car wash is a linear function of the capacity of the tank. the costs of a fill-up and a car wash for three different customers are shown in the table. write an equation for the function in slope-intercept form. then, find the cost of a fill-up and a car wash for a customer with a truck whose tank size is 25 gallons.

Step-by-step explanation:

To right the linear equation in slope-intercept form, we first need to find the slop, which is defined

Now, we choose to points from the table and . Using this points, we calculate the slope.

Now, using one point and the slope, we find the point-slope form, which is gonna give us the slope-intercept form:

Therefore, the right choice is the first one, because it's the only one that has this linear equation.

In addition, to find the cost for a car with 25 gallons of gas size, we just have to replace this number in the x-variable:

Therefore, the cost for a truck with a tank size of 25 gallons, is $55.75.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
