Answer:
The sale price of the coat is $187.50.
Step-by-step explanation:
Given:
A coat and a pair of boots are on sale for 20% off.
The regular price of the coat is $225. And the regular price of the boots is 130.
Now, to find the sale price of the coat.
Let the sale price of the coat be [tex]x[/tex].
Sale off = 20%
And the regular price of coat = $225.
According to question:
Sale price + sale off = Regular price.
[tex]x+20\%\ ofx=\$225[/tex]
⇒[tex]x+\frac{20}{100} \times x=225[/tex]
⇒[tex]x+0.20x=225[/tex]
⇒[tex]1.20x=225[/tex]
Dividing both sides by 1.20 we get:
⇒[tex]x=\$187.50[/tex]
Therefore, the sale price of the coat is $187.50.
