On tax free weekend, Alyssa bought 3 pairs of blue jeans for $92.31. The cost of the jeans is proportional to the number of pairs of jeans bought. What is the constant of proportionality in terms of dollars per pair of jeans?

constant of proportionality is 30.77 dollars per pair of jeans

Step-by-step explanation:

On tax free weekend, Alyssa bought 3 pairs of blue jeans for $92.31. The cost of the jeans is proportional to the number of pairs of jeans bought

Let c be the cost and 'n' be the number of jeans

cost 'c' is proportional to the number of jeans 'n'

where 'k' is the constant of proportionality

we need to find out k when c= 92.31  and n= 3

divide both sides by 3

k=30.77

so constant of proportionality is 30.77 dollars per pair of jeans

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.
