use the information above to answer the following questions.
1. a customer has $75 to spend for a pizza party and knows she needs 3 supreme pizzas. jacob tells her she can also afford to buy 4 dessert pizzas. is this reasonable? justify your response using estimation. if the answer is not reasonable, identify the error and then calculate the correct solution.
2. a family comes in with a coupon for $5 off any purchase and wants to know how much it will cost for 1 large supreme pizza and 1 order of cheese sticks if they use their coupon. jacob says it will be $17.89. is this reasonable? justify your response using estimation. if the answer is not reasonable, identify the error and then calculate the correct solution.
3. a customer calls in a delivery order for 3 large cheese pizzas and 2 dessert pizzas. the customer wants to give a 20% tip to the delivery driver. jacob says that $5 would be about 20%. is this reasonable? justify your response using estimation. if the answer is not reasonable, identify the error and then calculate the correct solution.
4. the largest order last saturday was from a basketball team that ordered 5 large supreme pizzas, 5 large cheese pizzas, 5 orders of cheese sticks and 5 dessert pizzas. jacob said the total was about $225. is this reasonable? justify your response using estimation. if the answer is not reasonable, identify the error and then calculate the correct solution.
5. adding additional toppings to a large cheese pizza cost $1.39 per topping. the equation 14.85 + 1.39x = 20 can be used to determine the number of toppings that can be added to a large cheese pizza for a total of $20. jacob solves the equation and says you can get 4 toppings added if you have $20. is this reasonable? justify your response. if the answer is not reasonable, identify the error and then calculate the correct solution.
