Answer:
The original price for this dress was $30
Step-by-step explanation:
If 90% of 30 is 27, we have to find out 10% of 30.
How to find it:
1) You make the 10% of 30 into a proportion
10/100=x/30
(Cross multiply)
100x=300
x=3
2) So now since we’ve found 10% of 30, we add it on to 27.
27+3=30
Therefore, the original price of the dress that Kate bought was $30.
