Step-by-step explanation:
Yes, there is a proportional relationship between the number of cinnamon rolls and the cost.
To determine the unit rate, we can compare the cost of one cinnamon roll to the cost of four cinnamon rolls.
If one cinnamon roll costs $2.50 and four cinnamon rolls cost $10.00, we can divide the cost of four cinnamon rolls by four to find the unit rate:
Unit Rate = Cost of Four Cinnamon Rolls / Quantity of Four Cinnamon Rolls
Unit Rate = $10.00 / 4
Unit Rate = $2.50
Therefore, the unit rate for cinnamon rolls is $2.50 per cinnamon roll.
