Question

math is ahrd for me and i need this answer

Answer 1

To find the percent increase, we can use the formula:

(final value - starting value) divided by starting value.

The final value is 3.34, and the starting value is 2.78, so final value minus starting value is 3.34-2.78 = 0.56.

We also need to divide this by the starting value:

0.56/2.78 = 0.2

Now we need to write the answer as a percentage, which we can do by multiplying 0.2 by 100%

0.2 • 100% = 20%
