To find the quotient, we can multiply the dividend (-7) by the reciprocal of the divisor (14/3).
-7 × (3/14) = -21/14 = -3/2
Therefore, the quotient is -3/2.

28 oz. of cereal for $4.29
32 oz. of cereal for $4.59
32 oz. of cereal for $4.59
36 oz. of cereal for $4.79
36 oz. of cereal for $4.79
24 oz. of cereal for $3.59
To determine the best buy, we can compare the cost per ounce of each cereal.
For the first option, 28 oz. of cereal for $4.29, the cost per ounce is 4.29/28 = $0.153 per ounce.
For the second option, 32 oz. of cereal for $4.59, the cost per ounce is 4.59/32 = $0.143 per ounce.
For the third option, 36 oz. of cereal for $4.79, the cost per ounce is 4.79/36 = $0.133 per ounce.
For the fourth option, 24 oz. of cereal for $3.59, the cost per ounce is 3.59/24 = $0.149 per ounce.
Therefore, the best buy is the third option, 36 oz. of cereal for $4.79.
