Question

a dietitian recommends consuming at least 64 ounces of water a day. how is this best expressed as an inequality?
a. ( w < 64 )
b. ( w > 64 )
c. ( w geq 64 )
d. ( w leq 64 )

a recipe requires at least 2 cups of flour. which inequality represents this?
a. ( f > 2 )
b. ( f geq 2 )
c. ( f leq 2 )
d. ( f < 2 )

Explanation:

Step1: Analyze first problem

"At least 64 ounces" means \( w \) is 64 or more, so \( w \geq 64 \).

Step2: Analyze second problem

"At least 2 cups" means \( f \) is 2 or more, so \( f \geq 2 \).

Answer:

c. \( w \geq 64 \)
b. \( f \geq 2 \)
