Using Proportions to Solve Problems - Item 33943
A fabric store prices cotton fabric using a proportional relationship between the length
of fabric (in yards) and the cost in dollars.
If 0.2 yards of fabric costs $1.50, what is the constant of proportionality?
What is the constant of proportionality?
Write your answer as a decimal.
dollars per yard



Answer :

To find the constant of proportionality between two quantities that are in a proportional relationship, we divide one quantity by the other.

In this scenario, we are given that 0.2 yards of fabric costs [tex]$1.50. The constant of proportionality will tell us the cost per yard. To calculate this constant, we use the following formula: Constant of Proportionality = Cost / Length Given: Cost = $[/tex]1.50
Length = 0.2 yards

Plugging the values into the formula, we get:

Constant of Proportionality = [tex]$1.50 / 0.2 yards Now, we will perform the division to find the constant of proportionality: Constant of Proportionality = 1.50 / 0.2 = 7.5 This means the constant of proportionality is $[/tex]7.50 per yard.

Write your answer as a decimal, the constant of proportionality is $7.50.
