A rental car company charges a fixed fee of $15.00 plus $.12 per mile. Write an equation to find the total cost, y, for any number of miles, x
y = 15 + 0.12x
To write an equation that relates the total cost, y, to the number of miles driven, x, we need to consider two components:
1. The fixed fee of $15.00, which is added regardless of the number of miles driven.
2. The additional cost per mile, which is calculated as $0.12 times the number of miles driven.
Combining these two components, we get the equation:
y = $15.00 + ($0.12 * x)
In this equation, y represents the total cost (in dollars) and x represents the number of miles driven. By plugging in different values for x, you can calculate the corresponding value of y.
