A children's dress was discounted at 60% on Children's Day on June 1st. This children's dress is cheaper than the original price after the discount, 72 yuan. What is the original price of this children's dress?
Solution: Let the original price be X yuan.
0.6X =X-72
0.6x-0.6x=x-0.6x-72
0 =0.4X-72
72=0.4X
72÷ 0.4 = 0.4X÷ 0.4
180=X
A: Original price 180 yuan.
