Mrs. Smith's class took a survey and found that 9 out of 13 students prefer two scoops of ice cream over one scoop. Based on this rate, if 104 students buy ice cream, how many will choose two scoops of ice cream?

Answer :

Out of 104, 72 will prefer two scoops of ice cream

Here, we want to calculate the number that will make a selection

From the question we have it that out of the 13 sampled, 9 preferred 2 scoops

Thus, out of the 104, the number that will prefer two scoops will be;

[tex]\begin{gathered} \frac{9}{13}\times104 \\ =\text{ 72} \end{gathered}[/tex]
