Question

Josh takes a load of dress shirts to the dry cleaners. The amount he pays for dry cleaning (

Answer 1

Answer:

$\frac{3}{2}$ 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 .

$x \propto y$

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 $f = \frac{3}{2} s$

where s is the number of shirts.

Compare $f = \frac{3}{2} s$ with x = ky .

Thus

$Cost\ per\ shirt =\frac{f}{s}= \frac{3}{2}$

$k = \frac{3}{2}$

Therefore $\frac{3}{2}$ is the constant of proportionality in terms of the cost per shirt .

Answer 2

The amount he pays is the number of shirts times 3 / 2 (or 1.5) 
unless the equation is f=3/(2s) where the cost would then be the number of shirts times two, divided by three
