Answer:
Mean is 18
Step-by-step explanation:

Find how much greater 20 is than 5
20-5=15
the % is of 5, so the percent is percent out of 5
20 is x% of 5 greater than 5
20=(x%)5+5
minus 5 both sides
15=(x%)5
divide both sides by 5
3=x%
percent means parts out of 100
x%=x/100
3=x/100
times 100 both sides
300=x
answer is 300%
