What percent of 60 is 15

What percent means x/100.

The word "of" means times.

The word "is" means equals.

So we have x/100 · 60 = 15 or 60x/100 = 15.

The rest of the work is attached below, just solve the equation.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
