Question

Tommy and Fred deliver newspapers. Together, they deliver 186 newspapers. if Tommy delivered 22% of the newspapers, how many newspapers did Tommy deliver? Round your answer to the nearest whole number.

Answer 1

Tommy delivered 41 newspapers

Explanation:

Step 1: We can convert the percentage to a decimal by either imagining the percentage sign as a decimal and moving it two places to the right or by simply doing the operation 22 / 100, since a percentage is out of 100:

22% = 22.0 = 0.22

22 / 100 = 11 / 50 = 0.22

Step 2: When dealing with percentage problems, we can use the phrase "y is P% of x" (P% of x is y also works) which allows us to create the equation: P%x = y, where

• P% is the percentage converted to a decimal,
• x is the "of" value,
• and y is the "is" value

Since we're that the pair delivered 186 together and Tommy delivered 22%, we're trying to find what value is 22% of 186. Thus, we can use the percentage formula above, allow y to represent the unknown, 186 to represent x, and 0.22 to represent P%:

0.22 * 186 = y

40.92

41 = y

Thus, Tommy delivered 41 newspapers.
