Answer 1

N 1

There are 36 students in Mrs. Young's 4th period class. Predict how many would choose mushrooms as their favorite topping.

looking at the table

mushrooms -----> 7%

we have that

36 students -------> represent 100%

applying proportion

36/100=x/7

solve for x

x=7*36/100

x=2.52 -------> 3 students

N2

There are 36 students in Mrs. Young's 4th period class. Predict how many would choose sausage as their favorite topping

looking at the table

sausage -------> 31%

36 students -------> represent 100%

applying proportion

36/100=x/31

solve for x

x=31*36/100

x=11.16 ------> 11 students

For N 3, N4, N5 the procedure is the same
