Answer:
Constant of proportionality is $6 for one pair and cost of dry cleaning 11 pairs of pants is $66.
Step-by-step explanation:
Dry cleaning fees is directly proportional to the charges of dry cleaning.
Cleaning fee ∝ Pairs of pants
Cleaning fee = k × Pairs of pants
where k is the proportionality constant.
If dry cleaning fee for 3 pairs of pants is $18 then from the equation given above
18 = k ×3
k = [tex]\frac{18}{3}=6[/tex]
SO the equation will be Cleaning fees = 6×Pairs of pants
For 11 pairs of pants,
Cleaning fees = 6×11 = $66
Therefore, constant of proportionality is $6 for one pair of pants and cost of dry cleaning 11 pairs of pants is $66.
