The last one is 1 I believe
1/2 dude that is he awnsner to the queston
Current price is $14.98.
$14.98/.50 = $29.96. This was the price after the 20% mark down. Now calculate the original as follows:
$29.96/.80 = $37.45. This is the original price before all the discounts.
I believe the answer for the first question is A. but not 100% sure, it's the only one I can figure out to be right.
The answer for the second question is C. 90% of 30 is 27.
I hope this helps.
