A. Matthew is spending $5 per hour.
B. Mitchell is spending less money per hour than Matthew.
C. Mitchell is spending his money at a faster rate than Matthew.
D. The rate of change represents the amount of money spent playing video games per hour.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
