Question

to make a small vase, elisa uses no more than 4.5 ounces of clay. to make a large vase, she uses at least 12 ounces of clay. which compound inequality represents the number of ounces of clay, c, that elisa uses to make one vase of either size?
○ 4.5 < c < 12
○ 4.5 ≤ c ≤ 12
○ c < 4.5 or c > 12
○ c ≤ 4.5 or c ≥ 12

Explanation:

Step1: Define small vase clay limit

Elisa uses no more than 4.5 oz, so $c \leq 4.5$.

Step2: Define large vase clay limit

Elisa uses at least 12 oz, so $c \geq 12$.

Step3: Combine the two conditions

The clay used is for either a small or large vase, so we use "or" to combine the inequalities.

Answer:

D. $c \leq 4.5$ or $c \geq 12$
