$7.7

Explanation:

Hello, I can help you with this

you can solve this by using a simple rule of three.

Step 1

define

if the wholesale price for a shirt is $5.50,it is 100 percent

$5.50⇔100%

the new price(x) is 40% more than the original, it means 140%

x ⇔ 140%

the relation is

`(5.5)/(100)= (x)/(140)\\`

Step 2

solve for x(isolate x)

`(5.5)/(100)= (x)/(140)\\x=(5.5*140)/(100)\\x=7.7`

the price of the shirt in the department store is $7.7

Have a nice day.
