Consider this conversation between two work colleagues:

Sarah: Hey Jason, what did you say you needed these other selling prices for again?

Jason: I$\text{'}$m trying to figure out if my potential customers will be willing to pay what I want to charge for my clever upgrade to

plastic storage containers.

Sarah: $,$ Oh$,$ wow, that sounds super exciting; thanks for including me in this analysis.

Jason: You just wait, Sarah. I$\text{'}$m going to make a dent in this market, and then we'll see who retires at age $45!$

Sarah gathered the following selling price information about other plastic storage containers on the market.

Competitor $913$ Plastic Containers with Lid

$$12,$ lid fits tightly but is not spill$-$proof

$$15,$ lid is spill$-$proof but snaps on loudly

$$10,$ lid just rests on top so is not tight$-$fitting

However, without access to competitors' internal records, she could not determine their costs.

Meanwhile, Jason made note of his production costs and secretly smiled to himself as he thought about what a great idea he had. He

wants to make plastic storage containers that have a locking lid. More than that, the lid locks quietly, so no one knows you're sneaking a

treat from the container $($yes$,$ Jason got busted stealing Sarah's famous chocolate cookies, and he vowed to fix this problem

permanently$).$ Here's his estimated costs to produce and sell one $913$ plastic container with quiet, spill$-$proof lid:. c$)$ After some additional research, Jason believes he'll be able to keep his costs down if he produces this type of product in multiple sizes to keep his equipment operating at full capacity, while providing the market place with several size options for these incredible containers. Assume that his estimated costs for a $9$x$9$ container and a $4\backslash$times $6$ container are $$13$ and $$16,$ respectively. What selling price would he charge for each of these containers, given the same $30\%$ desired markup? $($Round answers to $2$ decimal places, e$.$g$.15\mathrm{.}25.)$

$4$ x $6$ Container

$9$ x $9$ Container
