Question

A baker sells 4 cookies for $3. The price for 10 cookies is $6. Is the relationship

between the cost and the number of cookies proportional? Explain.

Answer 1

The relationship between the cost and the number of cookies is not proportional.

Step-by-step explanation:

The relationship between the cost and the number of cookies is not proportional. In a proportional relationship, the ratio between the cost and the number of cookies would remain constant. However, in this case, the price for 4 cookies is $3 and the price for 10 cookies is $6. Let's compare the ratios to see if they are equal:

For 4 cookies: $3/4 = $0.75

For 10 cookies: $6/10 = $0.6

Since the ratios are not equal, we can state that the relationship is not proportional.

Answer 2

Yes it is because you’re adding 6 more cookies for a few more dollars.
