Answer 1

Proportional pricing is present when the ratio of quantity to total cost remains constant across different quantities. The examples provided indicate nonproportional pricing since the prices per orange in each case were different.

Step-by-step explanation:

To determine if the pricing of oranges at different markets is proportional or nonproportional, we analyze the relationship between the number of oranges and the total cost. If the ratio of the number of oranges to total cost is the same for each comparison, the pricing is proportional; otherwise, it's nonproportional.

Let's examine two of the given examples:

For 10 oranges at $6.50 and 15 oranges at $10.25, we can compute the price per orange for each case ($6.50/10 = $0.65 per orange and $10.25/15 = $0.683 per orange). Since the prices per orange are not equal, this market uses nonproportional pricing.

For 5 oranges at $9.75 and 10 oranges at $13.00, we compute the price per orange for both cases ($9.75/5 = $1.95 per orange and $13.00/10 = $1.30 per orange). Again, as the prices per orange differ, this market also uses nonproportional pricing.

To confirm proportional pricing, all comparable pairs of quantity and cost would need to result in the same price per orange.
