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.

The correct answer is: "Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce."

In order to find the rounded cost per one item (in this case, per one ounce) Susan needs to divide the total price between the number of units and after that, round the result obtained up to the nearest cent.

Therefore:

Brand A

2.55$/12 ounces= 0.2125 $/ounce

As the third decimal digit, 2, is closer to 0 than to 9, then we maintain the second decimal digit as 1.

The price per unit of brand A after rounding it up is 0.21 $ per ounce

Brand B

1.45$/8 ounces= 0.1812

As the third decimal digit, 1, is closer to 0 than to 9, then we maintain the second decimal digit as 8.

The price per unit of brand B after rounding it up is 0.18 $ per ounce
