Answer 1

Okay so first we need to write the algebraic expressions

Answer 2

Good, but remember to use the variable m for the mileage, if you don't, you'll confuse yourself with a 2 variable inequality. It would be m+109 and 0.80m+65. Now the question is for what mileage will company A be less than company B. So you would have to set it as an inequality. Do you know what that inequality would be?
