Answer:

a = 55

Explanation:

1. Set up the equation: 0.2a = 11 (20% is equal to 0.2 because to convert a percentage to a decimal you divide it by 100. In math, "of" means "times" and "is" means "equals" so the equation is 0.2 x a = 11, which can be shortened to 0.2a = 11).

2. Divide both sides by 0.2. You will be left with a = 55.
