Answer:
54 dollars
Step-by-step explanation:
This is the price AFTER the discount
Let x be the price before the discount
-------------------------------------------------------
Price after discount = (price before discount) - (10% of price before discount)
54 = (x) - (10% of x)
54 = x - 0.10x
54 = 0.90x
0.90x = 54
0.90x/0.90 = 54/0.90 Divide both sides by 0.90 to isolate x.
x = 60
So the price before the discount was $60.
