Question

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?

Answer 1

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.
