Question

PLEASE HELP ME ! (I AM TERRIBLE AT MATH)

A public opinion survey is administered to determine how different age groups feel about an increase in the minimum wage. Some of the results are shown in the table below.

For - Against - No Opinion
(21-40 yrs old) 0 20 5
(41-60 yrs old) 20 0 20
(over 60 yrs old) 55 15 5

The survey showed that 40% of the 21 - 40 year-olds surveyed are against an increase, and 15% of the entire sample surveyed has no opinion.

How many 21 - 40 year-olds surveyed are for an increase? (_____________)

How many 41 - 60 year-olds are against an increase? (_____________)

Answer 1

It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15. 

You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully
