Question

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?

Answer 1

Answer:

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'

$c=k \cdot n$

where 'k' is the constant of proportionality

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

$c=k \cdot n\\92.31=k \cdot (3)$

divide both sides by 3

k=30.77

so constant of proportionality is 30.77 dollars per pair of jeans
