If a dress is sold for #3800.00 at a 20% discount. what is its original price?
A
#3,000.00
B
#4,000.00
C
#5,000.00
D
#4,750.00
correct option: d
Given that the cost of the dress reduces to #3800.00 by the discount,
Assume the original price = x
x – (20% of x) = 100
x – 0.2x = 100
0.8x = #3800
x = \(\frac{3800}{0.8}\)
x = 4,750
