Luca bought a crystal vase that was marked down 40% from an original price of S100. If he paid 10% sales tax, what was the total cost of the crystal vase?

First, find what is 40% of the original price equal to:


0.4*100=40

Substract $40 from the original price:


100-40=60

Calculate 10% of the new price of $60:


0.1*60=6

Add $6 to the price of $60:


60+6=66

The total cost of the crystal vase is $66.
