If a dress is sold for #3800.00 at 20% discount. what is its original price?
A
#3,000.00
B
#4,000.00
C
#5,000.00
D
#4,750.00
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
It is given that the cost of the item reduces to #3800.00 after the discount on the item.
Let original price = x
x – (20% of x) = 100
⇒ x – 0.2x = 100
⇒ 0.8x = #3800
⇒ x = \(\frac{3800}{0.8}\)
⇒ x = 4,750
