Question

The school store sells pencils for $0.30 each, hats for $14.50 each, and binders for $3.20 each. Elena would like to buy 3 pencils, a hat, and 2 binders. She estimated that the cost will be less than $20.

1. Do you agree with her estimate? Explain your reasoning.

2. Estimate the number of pencils could she buy with $5. Explain or show your reasoning

Answer 1

1. No I do not agree with her estimate, because after adding up all of the cost of the things she wants to purchase, the cost will be over 20 dollars.

2. With 5 dollars she could buy 16 pencils. .30x16=4.80, so she could buy 16 pencils
