Question

Larry has $20 to spend at the store. He plans to purchase five items that cost $5.79, $7.63, $3.46, $2.99, and $3.65. Larry estimated his total cost to make sure he has enough money for his purchases. Is his estimate accurate? Explain why or why not.

Answer 1

He does not. 5.79 + 7.63 + 3.46 +2.99 + 3.65 is equivalent to $23.52. And on top of that you don’t know if it’s before or after tax.

Answer 2

Answer:Sample Response: Larry did not round correctly. He used front-end estimation, but he did not round up when appropriate. His estimate will be lower than the amount of money he needs.
