Background

Employees often have to pick among several health insurance plans offered by their employer. Different plans are better

for different circumstances, like whether or not you are covering a family and the amount of doctor visits you expect to

make. For our purposes, there are three attributes of an insurance plan that are important:

$$ The premium: this is how much you have to pay for a year of insurance.

$$ The deductible: this is how much you have to pay for your doctor's bills before insurance will start paying anything.

For example, if you have a $$1000$ deductible, then your first $$1000$ worth of doctor's bills during the year will be

your responsibility to pay. If you have less than $$1000$ in expenses during the year, then your insurance will not pay

anything toward your bills. Otherwise, you pay the first $$1000$ and you and your insurance company split the cost

for the rest of the bills. How those bills are split is determined by the...

$$ The coinsurance: this is a percentage, like $20\%.$ After you have "met your deductible"$--$that is$,$ paid doctor's bills

totaling your deductible amount$--$then the remaining bills for that year are split. You pay the coinsurance, and your

insurance company covers the rest.

Here are a few examples:

$1.$ My plan has $$5000$ premium, $$1000$ deductible, and $20\%$ coinsurance.

a$.$ If I have no medical bills, then my health care costs are $$5000($i$.$e$.,$ just the premium$).$

b$.$ If I have $$500$ in medical bills, then I pay all of those $($because they are less than the deductible$),$ plus the premium.

My health care costs are $$5500.$

$2$

c$.$ If I have $$1002$ in medical bills, then I pay the premium, plus my $$1000$ deductible, plus $20\%$ of the bills over the

deductible $(20\%$ of $$2$ is $$0\mathrm{.}40).$ Thus, my health care costs are $$6000\mathrm{.}40.$

d$.$ If I have $$15000$ in medical bills, then I pay the premium, plus my $$1000$ deductible, plus $20\%$ of the bills over the

deductible $(20\%$ of $$14000$ is $$2800).$ Thus, my health care costs are $$8800.$

$2.$ In scenario $2,$ suppose my plan has $$3000$ premium, $$4000$ deductible, and $25\%$ coinsurance.

a$.$ If I have no medical bills, then my health care costs are $$3000($i$.$e$.,$ just the premium$).$

b$.$ If I have $$500$ in medical bills, then I pay all of those $($because they are less than the deductible$),$ plus the premium.

My health care costs are $$3500.$

c$.$ If I have $$1002$ in medical bills, then I pay all of those $($because they are less than the deductible$),$ plus the

premium. My health care costs are $$4002.$

d$.$ If I have $$15000$ in medical bills, then I pay the premium, plus my $$4000$ deductible, plus $25\%$ of the bills over the

deductible $(25\%$ of $$11000$ is $$2750).$ Thus, my health care costs are $$9750.$

Project Description

For this project, you will build a program that computes the health care costs given the premium, deductible, coinsurance,

and total medical bills. We will be working with two pre$-$defined health care plans, as well as letting the user enter their

own parameters. Here are the two plans:

Analysis

As you gain experience with programming, you will be able to analyze the description above and create a program to

compute the health care costs. In this first project, however, we will guide you through the analysis part and help you

design your program.

One of the first steps in analysis is determining the inputs that your program needs and the outputs it will produce. Before

reading the next part of the description, take a minute to write down the inputs and outputs.

You should have written down the following:

$$ Inputs: Premium, deductible, coinsurance, amount of medical bills

$$ Output: health care costs

Design

As with the analysis, as you gain experience with programming you will reach the point where you can complete the design

on your own. This is where you figure out the algorithm $($i$.$e$.,$ the steps the computer needs to take$)$ for computing the

health care costs for a given premium, deductible, coinsurance, and amount of medical bills. You can use the definitions

and examples above to figure this out, along with the requirements that follow.

Your program should meet the following specifications. $($The amount of points for each part is in square brackets$).$

$[10$ pts$]$ As with all your code, correct compilation is critical.

$$ Commenting and style

o $[3$ pts$]$ Comments should be clearly written with correct grammar and spelling.
