Question

Susan needs 228 ounces of fruit juice for a party. She is choosing between two brands of juice.

Two Brands of Juice
Brand A
Brand B
12 ounces
8 ounces
$2.55
$1.45

She finds the unit rate of each brand and rounds to the nearest cent. Which statement about the unit rates is true?
Brand A costs approximately $0.18 per ounce, and Brand B costs approximately $0.21 per ounce.
Brand A costs approximately $0.12 per ounce, and Brand B costs approximately $0.15 per ounce.
Brand A costs approximately $0.15 per ounce, and Brand B costs approximately $0.12 per ounce.
Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce.

Answer 1

Answer: To find the unit rate for each brand, we need to divide the cost of each brand by the number of ounces in each container:

Unit rate for Brand A = $2.55 ÷ 12 ounces ≈ $0.21 per ounce

Unit rate for Brand B = $1.45 ÷ 8 ounces ≈ $0.18 per ounce

Therefore, the statement that is true about the unit rates is:

Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce.

So, if Susan wants to get the most juice for her money, she should choose Brand B, which has the lower unit rate.

Note that the cost per ounce for each brand is not rounded to the nearest cent, but rather to two decimal places.
