A dress was reduced from $180 to $162.
Express the discount as a % of the original price.

The original price was discounted by 10%

Step-by-step explanation:

180-162 =  0.1  

1-0.1= 0.9

0.9 * 100= 90%

100% -10%= 90%

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.
