Answer 1

D. a 9 OZ box of rice for $1.25

Explanation:

This is correct because if you divide each one of the answers D has a better unit rate.

A. $2.42 divided by 16= unit rate of $0.14

B. $1.93 divided by 12= unit rate of $0.16

C. $0.90 divided by 6= unit rate of $0.15

D. $1.25 divided by 9= unit rate of $0.13

Answer 2

find the unit price

2.42/16 = 0.15125

1.93/12 = 0.15083 repeating

0.90/6 = 0.15

1.25/9 = 0.138 repeating

The $1.25 one for 9 Oz would be the best buy.
