A local coffee shop is running a promotion. They charge $2 for a small coffee and $3 for a large coffee. On Tuesday, they need to make $600 to cover costs. Write a linear equation in standard form to represent the number of small (x) and large (y) coffees they need to sell to meet their goal.
A taxi service charges a flat fee of $3 plus $0.50 per mile. Write a linear equation in slope-intercept form that represents the total cost (y) of a taxi ride for x miles.
