Answer:
25%
Step-by-step explanation:
To calculate the percent of change you divide like this:
[tex]\frac{20-16}{16}[/tex]
= [tex]\frac{4}{16}[/tex]
Simplify:
[tex]\frac{4}{16}[/tex] ÷ [tex]\frac{4}{4}[/tex] = [tex]\frac{1}{4}[/tex]
To turn it to a percent, multiply the fraction by a number that will turn the denominator into 100:
[tex]\frac{1}{4}[/tex] × [tex]\frac{25}{25}[/tex]
= [tex]\frac{25}{100}[/tex]
[tex]\frac{25}{100}[/tex] = 25%
