Answer:
0.40x
Step-by-step explanation:
If x is the original price, 60% of x is 0.60x. When that is subtracted from the original price, the sale price is ...
sale price = x - 0.60x = (1 -0.60)x
sale price = 0.40x
_____
Full price is 100% of x. If the price has been reduced 60%, then 40% of the original price remains as the sale price.
