Question

approximately 2000 tires are recycled to produce one lane-mile of asphalt rubber. Enter an expression in the box for the number tires used to make x lane-miles of asphalt rubber 

Answer 1

This means that for every lane-mile of asphalt rubber, you multiply by 2000 to get the number of tires used. For example, if you wanted to find out how many tires are used for 3 lane-miles of asphalt rubber, you would substitute x with 3 in the equation. So, T = 2000 * 3 = 6000 tires. This is a linear relationship between the number of lane-miles and the number of tires used.
