Question

A jeweler orders necklaces from a website that offers $6 shipping for any-size order. Each necklace costs $7. The jeweler wants to know the total cost of ordering n necklaces. What is the independent (input) variable? What is the dependent (output) variable?

Answer 1

The independent input is the cost of each necklace because you can buy a lot of jewerly and have the cost multiplied by how much they are going to buy. But the $6 of shipping is the dependent because you can as many jewerly as you want but the shipping amount multiplies depending on how much jewerly the person will buy.
