Writing Linear equations and functions and not functions

Uber charges $2.00 plus $0.15 per mile while Lyft charges $1.50 plus $0.20 per mile. Write an equation to show the same price.

ANSWER: U = L

2 + .15x = 1.50 + .20x​

​Example

When writing the equation always write the problems given objects' first initials.Then use given information to write. Your unknown is always x (in some cases they say "per"). Make sure to include =!
