Kate paid $27 for a dress that was on sale at 10% off. What was the original price for this dress?

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.

$30

Step-by-step explanation:

The dress was 10% off, so 100% - 10% = 90%

90% is what percent she paid for the dress.

$27 is 90% the original price.

27/x = 90/100

90x = 2700

x = 30

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
