Respuesta :

Here is the solution...

You have $40 to spend "n" number of gallons of gas.

Each gallon of gas costs $3.25.

Total amount = 3.25 * the number of gallons.

Therefore, the equation   40 = 3.25n

Here the variable "n" represents the number of gallons that we can buy for $40.

The slope 3.25 represents the cost per gallon.
