Question

An ice cream stand charges $2 for a kiddie cone and $6 for a large cone. Clara creates two patterns to compare the costs. She writes ordered pairs in the form (kiddie cone cost, large cone cost) for the corresponding numbers of cones. Which ordered pairs could be on Clara's list? Circle all the correct answers. 3 A (6, 12) B (8,24) C (12,36) (16,42)​

Answer 1

Answer: B and C

Step-by-step explanation: The second number (that represents the large cone) will be 3 times greater. the ratio of the ordered pairs = 1:3.

Answer 2

• B (8, 24)
• C (12, 36)

Explanation:

To find the ordered pairs that could be on Clara's list, we can use the following order pair:

( Number of kiddie cones ×Cost of a kiddie cone , Number of large cones × Cost of a large cone)

We know that the cost of a kiddie cone is $2 and the cost of a large cone is $6. We also know the order pair:

For 1 ice cream

Order pair: ( 1 × $2, 1 × $6 ) = ($2,$6)

For 3 ice cream

Order pair: ( 3 × $2, 3 × $6 ) = ($6,$18)

For 4 ice cream

Order pair: ( 4 × $2, 4 × $6 ) = ($8,$24)

For 6 ice cream

Order pair: ( 6 × $2, 6 × $6 ) = ($12,$36)

For 8 ice cream

Order pair: ( 8 × $2, 8 × $6 ) = ($16,$48)

Therefore, the only possible ordered pairs are:

• B (8, 24)
• C (12, 36)
