Is the value of the new amount greater than or less than the value of the original amount?

The percent of increase is about 60 %.

Practice makes perfect
To determine percent change p, we can use the following general formula. p % =Amount of increase or decrease/Original amountFrom the given values, we can see the original amount was 78 and the new amount is 125. This is an increase in the amount. 125-78= 47 The difference between the new amount and the original amount is 47. Now we can use the formula.
Percent change=Amount of increase/Original amount
Percent change=47/78
Percent change=0.602564...
Percent change ≈ 0.60
Percent change ≈ 60 %
The percent of increase is about 60 %.
