The pizza delivery guy charges a flat rate of $2 plus $8 per pizza. Use x for the number of pizzas purchased. Write an equation to show how much money (y) is charged to deliver (x) pizzas.

• y = 2x + 8

• y = 2 + x +8

• y = 2 + 8x

• 8 = 2x + y

Tom has a $2.00 coupon off any order. He decides to buy Sour Patch Kids for $3.75 per pound. Use x for the number of pounds of candy he will buy. Write an equation to represent the cost (y) the Tom spent on candy.

• y = 2x + 3.75

• y = 2x - 3.75

• y = 3.75x + 2

• y = 3.75x - 2
