Answer:
0.45
Explanation:
Given data
cost of 12 oz of honey = $5.40
Let us find the cost per oz of honey bear
cost per oz= 5.40/12
cost per oz= $0.45 per oz
hence the constant of proportionality for the situation is 0.45
to find the cost for any number of oz, simply multiply the amount of oz by 0.45
