Answer:
D) $60.40
Step-by-step explanation:
The price is marked up by 20%. If we say the original price is P, then the new price is P + 0.2P = 1.2P. So the new price must be a multiple of 1.2.
If we divide each option by 1.2:
A) $1.20 / 1.2 = $1.00
B) $70.80 / 1.2 = $59.00
C) $6.00 / 1.2 = $5.00
D) $60.40 / 1.2 = $50.333...
E) $150.60 / 1.2 = $125.50
Option D can't be the new price. There's no such thing as a one-third penny.
