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

answer: d. $20

step-by-step explanation:

just took the test

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
