Answer:
30%
Step-by-step explanation:
One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.
If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.
10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%
3.76-4.7 = $3.29
With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.
