Answer:
100
Explanation:
To increase 80 by 25%, you need to add 25% of 80 to 80.
First, we find what 25% of 80 is.
To find a percent of a number, multiply the percent by the number.
Change the percent to a decimal by dividing the percent by 100.
25% of 80 = 25% × 80 = 25/100 × 80 = 0.25 × 80 = 20
25% of 80 is 20.
Now we add 20 to 80.
80 + 20 = 100
