Question

Mike surveyed 250 teenagers to find out their favorite food. He found that 76% of the teenagers surveyed like burgers.

Part A: How many teenagers surveyed like burgers? Show your work. (4 points)

Part B: In another survey, Jane found that 25% of the total number of teenagers surveyed like sandwiches. If 50 teenagers like sandwiches, what is the total number of teenagers that Jane surveyed? Show your work. (4 points)

Part C: Give an example of a situation in which a percentage is greater than 100%.

Answer 1

Part A
Since there's 76% who like burgers, you have to multiply the number of participants to the percentage, but first you have to convert the percent to decimal.

250
× .75
_________

190.00

A. 190 participants like burgers.

Answer 2

Part B.

To get the total number of participants, you have to divide the number of result to the percentage. First, transform the percent into decimal. The percent will be the put outside the division sign while the number of result will be inside. Then, move the decimal backwards so that it would become a whole number.

So,

.25 will be 25

Since you move two places in decimal, you have to do the same with the result that is inside the division sign.

So,

50 will become 5000

Then divide it.

5000÷25= 200

B. Jane surveyed 200 participants.

Answer 5

suppose you own a hot dog wagon and sell the following:

10 hot dogs in the morning

30 hot dogs in the afternoon

The number of hot dogs you sell in the afternoon is 300% of the number you sold in the morning. It’s three times as many. (Ctto. from www.dummies.com)
You can change the given. That's just an example though.
