Answer:
[tex]\frac{3}{2}[/tex] is the constant of proportionality in terms of the cost per shirt .
Step-by-step explanation:
Constant of proportionality
Let us assume that x is proportional to y .
[tex]x \propto y[/tex]
x = ky
Where k is the constant of proportionality .
As given
Josh takes a load of dress shirts to the dry cleaners.
The amount he pays for dry cleaning f is given by the equation [tex]f = \frac{3}{2} s[/tex]
where s is the number of shirts.
Compare [tex]f = \frac{3}{2} s[/tex] with x = ky .
Thus
[tex]Cost\ per\ shirt =\frac{f}{s}= \frac{3}{2}[/tex]
[tex]k = \frac{3}{2}[/tex]
Therefore [tex]\frac{3}{2}[/tex] is the constant of proportionality in terms of the cost per shirt .
