Answer:

The answer is 40%

Step-by-step explanation:

You first multiply the amount of people surveyed by the decimals shown...250×0.34=85 250×0.06=15 Add them together 85+15=100

Next you divide your answer(100) by 250 which will give you 0.4

Finally, multiply 0.4 by 100 to make it a percent

Your final answer will be 40.
