On January 1, 2020, the merchandise inventory of Ivanhoe, Inc. was $1700000. During 2020 Ivanhoe purchased $3398000 of merchandise and recorded sales of $4200000. The gross profit rate on these sales was 20%. What is the merchandise inventory of Ivanhoe at December 31,

2020? $1738000. $3360000. $840000. $802000.

This assignment is For a C++ class , I am having difficulty with getting the boolean statements the most; getting them set up properly inside the int main() area.

You have been asked to define a tip-calculating function named calcTip that could be integrated into a larger piece of software designed to improve guest service at a restaurant. As a result, you must conform to the function specification used throughout the rest of the project's code:

double calcTip(double checkAmount, bool postTax, bool round);

This function, when called, calculates and returns a tip amount in U.S. dollars determined by the values of its two boolean parameters. Any extra comments with guidance will be very apprectiated, thank you so much!
----

tipCalc's parameters:

checkAmount:

The amount of a check in U.S. dollars with tax included.
Ex. a value of 15.00 represents $15.00 USD.

postTax:

The value of the postTax parameter determines whether the function calculates a tip before or after the tax has been added to a check amount.

A value of true means that the calculated tip will be based off the entire check amount.

A value of false indicates that tax must be removed from the check amount before a tip is calculated.

round:

The value of the round parameter determines whether or not the tip amount is rounded up before being returned. A value of true indicates that the value will be rounded up.

----

Assume that the tax rate for meals is a fixed 7.8% regardless of the geographical region in which
this software may be used. Also, in the interest of elevating the standard of what constitutes a
good tip, the tip rate is a fixed 20%.

As examples, a tip calculated for an entire $20.00 check (which includes tax) without rounding would be $4.00. A tip calculated for only the pre-tax amount of a $20.00 check without rounding would be $3.69.

Implementation

You must not make any changes to the calcTip's return type or parameters.

----

In main, you must prompt for and accept user input that will be used as arguments for a calcTip function call.

You have the freedom to structure main as you see fit, provided that I can execute your program and specify the following before a call to calcTip is made:

1.) the amount of the check after tax has been applied (e.g. I can enter $20.00 or similar)
2.) whether or not I want my tip to be calculated off the full check (i.e. including tax)
3.) whether or not I want to round up my tip to the nearest U.S. dollar

You must not prompt for this input inside calcTip().

----

Once this is done, a function call to calcTip must be made inside main; its return value
will be output.

Results

Output the following text in main after making the call to calcTip:

Your tip amount is $[TIP AMOUNT]

In order to verify program correctness, you should run the program four times under the following conditions:

1.) The user wants a 20% tip on a $15 check before tax with no rounding.
2.) The user wants a 20% tip on a $15 check after tax with no rounding.
3.) The user wants a 20% tip on a $15 check before tax with rounding.
4.) The user wants a 20% tip on a $15 check after tax with rounding.

4. Suppose GDP is $800 billion, taxes are $150 billion, private saving is $50 billion, and public saving is $20 billion. Assuming this economy is closed, calculate consumption, government purchases, national saving, and investment.

Using the method of recursion, compute y[n] for n = 0 to 20, when x[n]=u[n] and y[-1]=2:

?[? + 1] − 0.8?[?] = ?[?]

Find a closed-form expression for your result.

Let f be a continuous function on the closed interval [0,1] with a range also contained in [0,1]. Prove that f that there exists an x in [0,1] such that f(x)=x. Is the same explanation still valid if f is not continuous?

5. Find a closed-form formula for the exponential generating function for the number of strings of length n with symbols a, b, c, where (number of a′s) + (number of b′s) ≥ 1; and, # c′s = even
