JavaScript calculator and basic HTML page

Hi -

I'm hoping for a simple calculator to be built based on the logic in an excel spreadsheet (attached)

Just look at the "100% calculated" section to see how it works... Both the Young/old sections are just examples and do the same function.

The form should have 5 inputs:

Marginal Cost

Current Price

Current Quantity

New Price

New Observed Quantity

Once the user enters these fields, there needs to be a calculate button, which on execute displays the output either beside or below (while keeping the inputs visible so they can be updated again).

Output fields are:

Optimal Price

Optimal Quantity


The page should be simple in design (all black) with nicely but designed grey/white input fields.

Font: Normal 1em/1.5 "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial.

I'm OK if the other fields in the excel exist (and are calculated but hidden) as I may use them as a follow up project.

Ideally, longer term I'd like the output to also show equation steps and perhaps a graph... but that is probably a bit more complex and not in current scope.
