`=18.95`

The number of shorts kwan bought is

`=3`

The price of one short is

`15.50`

The amount kwan gave to the cashier is

The formula below is used to calculate the amount of change to be collected

`\text{change}=\text{Amount given to cashier -(amount of short+amount of shirt)}`

The amount for 2 shirts will be

The amount for the 3 shirts will be

`\begin{gathered} =3*15.50 \\ =46.50 \end{gathered}`

By substituting the values in the formula, we will have

Hence,
