Question

a small town has a population of 3200. 30% of the townspeople speak Italian, 20% speak French, and the rest do not speak either of these languages. 360 people speak both italian and french. What percent of the townspeople speak only Italian?

Answer 1

%18.75

Explanation:

360 is 11.25% of 3200. If you subtract 11.25 from 30, you get 18.75. So 18.75 percent of the townspeople speak only italian,

More in depth and another way to solve:

the 30% is the amount of people that speak italian. And that 30% is split into two groups. The people that ONLY speak italian. and the people that speak BOTH italian and french.

By doing a little calculation, you find out that 960 people in the town speak italian. 360 of these people also speak french. So in order to find the amound of people that ONLY speak Italian, subtract 360 from 960 to get 600. 600 people in the down ONLY speak Italian, and not french. 600 is 18.75% of 3200, so 18.75% of the townspeople speak only Italian

Did that make sense?
