A gift store sells keychains for $3 each and picture frames for $9 each. Part A.
Write a number pattern for the cost of 0,1,2,3,4, and 5 keychains. Then write a second number pattern for the cost of 0,1,2,3,4, and 5 picture frames.

Part B.
How do the corresponding terms of the two number patterns compare?​

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
