Answer:
28%
Step-by-step explanation:
We get 30% off the original price
The new price is (100-30) = 70$ of the original price
Let x = the original price
The new price is .7x
Now get get an additional 60% off. We pay (100-60) = 40 percent of the price
Take .7x * .4
The new price is .7*.4 x
.28x
This is 28 percent of the original price x
