Answer 1

Part A:
A pound is a larger unit than an ounce, so multiply the number of pounds by 16 to find the number of ounces. Therefore, 2 pounds is equal to 32 ounces.

Part B:
Renee's mother uses 4 ounces of coffee per day. In a week, she would use 4 ounces x 7 days = 28 ounces of coffee. Renee bought her mother 32 ounces of coffee, which is more than enough for a week. Therefore, yes, Renee bought her mother enough coffee for a week.

Answer 3

Part A:
To convert ounces to cups, divide the number of ounces by 8.

Part B:
The 4-cup carton equals 32 ounces (4 cups x 8 ounces per cup). The 15-ounce carton is equivalent to 15/8 = 1.875 cups. Therefore, the total amount of cream that Sean has is 4 + 1.875 = 5.875 cups. This is more than the 5.5 cups that his mother asked for, so the two cartons will be enough.
