Answer 1

109% of increase

Explanation:

In order to know the increase in the percentage, we can do this in various methods, however let's follow the method using only rule of 3; you can also do it by the variation index, however, rule of 3 is easier.

First, we need to know the difference between 756$ and 1580$:

1580 - 756 = 824$

Now let's set the rule of three, assuming that 756 is 100% innitial:

756$-------->100%

824$--------> X

Solving for X:

X = 824 * 100 / 756 = 109.9947%

And if you round this number: 109%
