Need help with setting up the y1= equation.

I can do the table. Just unsure how to plug in the numbers.

y = 5 + 1.24x

Step-by-step explanation:

Let x be the no. of thousand gallons

Then the cost, y, is:

y = 5 + 1.24 x

You have to pay $5 regardless of how much you order, and $1.24 each thousand gallon ( 1.24x for x thousand gallons)

Just plug in the no. of thosand gallons in place of x, y will be the cost

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
