Answer:
$7.7
Step-by-step 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
[tex]\frac{5.5}{100}= \frac{x}{140}\\[/tex]
Step 2
solve for x(isolate x)
[tex]\frac{5.5}{100}= \frac{x}{140}\\x=\frac{5.5*140}{100}\\x=7.7[/tex]
the price of the shirt in the department store is $7.7
Have a nice day.
