Question

Calculate the unit price to the nearest tenth of a cent, and determine the better or best buy based on price alone. (2 points)

5. Chen Wu is buying potato chips. The following sizes are for sale: 1.5 ounces, $0.65; 5.75 ounces, $1.30; and a 2-pack of the 5.75 ounces, $2.45.

Answer 1

Answer: To determine the unit price, we divide the price by the number of ounces.

For the 1.5-ounce bag:

Unit price = $0.65 / 1.5 ounces = $0.433 per ounce

For the 5.75-ounce bag:

Unit price = $1.30 / 5.75 ounces = $0.226 per ounce

For the 2-pack of 5.75-ounce bags:

Total ounces = 2 x 5.75 = 11.5 ounces

Total price = $2.45

Unit price = $2.45 / 11.5 ounces = $0.213 per ounce

Therefore, the 2-pack of 5.75-ounce bags has the lowest unit price and is the best buy based on price alone.
