<u>Answer:</u>
She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%
<u>Solution:</u>
A lady paid $26.35 for something that is usually $31, so she got a discount for the product.
Now, we have been asked to find out how much percentage discount she got.
To do that we first have to check how many dollars she got off the product.
To do so we have to subtract the discounted price from the initial price.
Therefore we get:
31 - 26.35 = 4.65
To find the percentage discount we need to do the following

Therefore she got a discount of 15%
Answer:
Blue: 13/100 = 0.13 = 13%
Purple: 130/100=1.3=130%
Step-by-step explanation:
The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
