Ok so you need an equation. 188.12 is the total cost he ends up paying. 17.95 is the base fee/y-intercept and the $0.91 for each mile driven is the slope. So, the equation will be like this: (total cost)=(slope)+(base fee) Now let’s plug in the numbers. 188.12=0.91x+17.95. Now we solve for x. (X represents the number of miles driven.
188.12=0.91x+17.95 (first subtract 17.95 from both sides of the equation) (after this you get 170.17=0.91x. (Now divide by 0.91 on both sides)
➳ These equations will have <u>infinite solutions</u> because they are in 2 variables. Any value can be substituted in the place of the variables x & y.
