The number of miles m that Lexus can skateboard in t minutes can be modeled by:
m = kt
It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.
Substituting:

Dividing by 20

Simplifying:

This produces the model

A better estimate would be something that is closer to one you had before...

To find the sale price<span> we can set up a proportion. 25/100 = </span>x<span>/48. We keep the 100 and 48 both on the bottom of the fraction since they </span>represent<span> the "whole". </span>x represents<span> the </span>discount<span> off the </span>full price<span> of the dress. To solve this proportion, we cross multiply, yielding 48 * 25 = 100x. Alternatively, </span>if<span> you notice that 25/100 ...</span>
