1 answer

To find the constant of proportionality in dollars per ticket, we first determine the cost of one ticket when buying a set of 3 raffle tickets for $5.00.

  1. Calculate the cost per ticket: \[ \text{Cost per ticket} = \frac{\text{Total cost for 3 tickets}}{\text{Number of tickets}} = \frac{5.00}{3} \]

  2. Perform the division: \[ \frac{5.00}{3} \approx 1.6667 \]

  3. Round to the nearest cent: \[ 1.6667 \approx 1.67 \]

Thus, the constant of proportionality in dollars per ticket is approximately $1.67.

The answer is B. $1.67.
