In a school with 400 students, a random sample of 40 students were asked which fruit is their favorite. Their responses are shown below. Apple - 10
Banana - 12
Peach - 8
Pear - 6
Strawberries - 4

Using proportional reasoning, about how many students in the school would you expect to select an pear as their favorite fruit?

60

Step-by-step explanation:

divide 400 by 40 you get the answer 10

now multiply 6 by 10 you get the answer 60 thats is the total pear fruit

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

answer: y=4000x+14000
