Answer 1

Answer:

• 6 oz: $0.60 per ounce
• 10 oz: $0.48 per ounce (best deal)
• 16 oz: $0.49 per ounce

Step-by-step explanation:

You want the price per ounce and the best deal, given 6-, 10-, and 16-ounce bricks cost $3.59, $4.79, and $7.89.

A. Unit Price

The unit price is found by dividing the price by the number of units. Here, our unit is 1 ounce, so we divide each price by the number of ounces to find the price per ounce. The calculator display attached shows the result to 4 decimal places. Here, we round to 2 dp.

• 6 oz: $0.60
• 10 oz: $0.48
• 16 oz: $0.49

B. Better deal

The lowest price per ounce is obtained with the 10 oz brick.
