Schools need to pay for bussing students around. They hire a company called School Bus Transport. It costs the school $7 for every student that they bus. Write an algebraic expression to represent this. Evaluate (or solve) the expression to find out how much it would cost to bus 260 students.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
