Answer:
The coat originally cost $20.
Step-by-step explanation:
The original cost is of x.
At a sale, coats were sold for $11 each. This price was 55% of a coat's original price.
This meas that:
[tex]0.55x = 11[/tex]
How much did a coat originally cost?
This is the solution for x for the equation above. So
[tex]x = \frac{11}{0.55} = 20[/tex]
The coat originally cost $20.
