Sebastian wanted to order pizzas for $7 each. The delivery charge is $3.50. He has $20.
Which number line shows the correct solution for how many pizzas he could order?
you answer would be c because if you take 7+7 you get 14+3.50 that is 17.5 if you take 20-17.5 you get 2.5 back you can not have a partial pizza so you will have to settle for just the 2
