Give your answer as an exact decimal or as a fraction in its lowest terms in the
form p/q.

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

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

median- 36f

mode - none

mean- 33.7 ~ 34f

the train arrives at 20: 27 hope i
