Answer:
$240
Explanation:
The sale price is 90% of the original price, so ...
$216 = 0.90 × original price
original price = $216/0.90 = $240
The original price of the set of dishes was $240.
240
If we get 10% off, we still have to pay 100-10 = 90%
Let x be the original price
x *90% = 216
.90x = 216
Divide each side by .90
.90x/.90 = 216/.90
x =240
The original price is 240
