At the fall festival, the student council sold 106 drinks and collected $265.00. The total amount collected is proportional to the number of drinks sold. What is the constant of proportionality in terms of dollars per drink?

Question

A.
3.5
B.
2.5
C.
2
D.
3

Answer 1

To find the constant of proportionality in terms of dollars per drink, we divide the total amount collected by the number of drinks sold.

The total amount collected is $265.00, and the number of drinks sold is 106.

So, we calculate the constant of proportionality \( k \) as follows:

\[ k = \frac{\text{Total Amount Collected}}{\text{Number of Drinks Sold}} = \frac{265}{106} \]

Now, we perform the division:

\[ k \approx 2.5 \]

Thus, the constant of proportionality in terms of dollars per drink is:

B. 2.5
