Answer:
A. 190 Teenagers
B. 200 Teenagers
C. A situation where we can have percentage greater than 100 % is found during increase in growth of population
Step-by-step explanation:
Part A.
Mike surveyed 250 teenagers to find out their favorite food. He found that 76% of the teenagers surveyed like burgers. Part How many teenagers surveyed like burgers?
We were told from the question, 76% of the teenagers surveyed loved burgers.
Total number of teenagers = 250
Therefore, the number of teenagers surveyed that loved burgers =
76/100 × 250
= 190 teenagers
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?
Let the total number of teenagers surveyed be represented by x
Therefore,
25% of x = 50 teenagers
25/100 × x = 50
25x/100 = 50
Cross Multiply
25x = 100 × 50
25x = 5000
x = 5000/25
x = 200
Therefore, 200 teenagers were surveyed
Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
A situation where we can have percentage greater than 100 % is found during increase in growth of population
