1. 60%

2. $500

Explained:

10% = 50 in this case since  50 multiplied by 9 is 450

50 multiplied by 10 is 500

Which concludes that $500 was the original price and it was discounted by $50!

3. 16.4%

Explained:

I'll be saying the price is $100 for an example

If 12% is taken off the price, you still have to pay 88%

So, 88% in decimal form is 0.88. 100 multiplied by 0.88 equals 88.

Now we have to take off the 5%

So, after 5% you'll still have to pay 95%, and 88 multiplied by 0.95 equals 83.6

Now, if you subtract the 100 minus 83.6, it equals 16.4

Which means your answer is 16.4%

Hope I helped!
