Answer:
None are correct.
Step-by-step explanation:
10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.
15/30 wanted cheese, so 1/2 wanted cheese.
5/30 wanted hamburgers, so 1/6 wanted hamburgers.
You can use this information to estimate the number of the 150 students who wanted each.
1/3 of 150 = an estimated 50 wants pepperoni
1/2 of 150 = an estimated 75 wants cheese
1/6 of 150 = an estimated 25 wants hamburgers
Now you can use this to see which one is true.
A. There are 40 students who want pepperoni
not true, there are 50
B. There are 100 students who want either pepperoni or hamburger
50(pepperoni) + 25(hamburger) = 75, so this is not true
C. There are 10 more students who will want cheese than hamburger
75(cheese) - 25 (hamburger) = 50, so this is not true.
D. There are 5 more students would want pepperoni than hamburger
50 (pepperoni) - 25 (hamburger) = 25, so this is not true
None of these answers are correct
