horrorfan [7]

Answer:

\frac{1}{4}+\frac{m}{2}   \leq x\leq 2

x denotes amount of food that Felicity's dog eats

Step-by-step explanation:

Given:

Felicity's dog eats no more than two cups of dog food per day.

Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats.

The amount of food that Martin's dog eats is represented by using m

To find: the inequality that represents the situation

Solution:

Amount of food that Martin's dog eats = m

Amount of food that Felicity's dog eats ≤ 2

Also,

Amount of food that Felicity's dog eats \geq \frac{1}{4}+\frac{m}{2}

Therefore,

\frac{1}{4}+\frac{m}{2}\leq Amount of food that Felicity's dog eats ≤ 2

Let x denotes amount of food that Felicity's dog eats.

\frac{1}{4}+\frac{m}{2} ≤ \frac{1}{4}+\frac{m}{2}   \leq x\leq 2
