Refer to the demand schedule below.
(a) Use the demand schedule to calculate total revenue and marginal revenue at each quantity.
(b) Plot the demand, total-revenue, and marginal-revenue curves.
Instructions: Round your answers to 2 decimal places. If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers.

Explanation:

Demand can be defined as the total quantity of a particular commodity which a consumer is willing and able to buy at a particular price and a particular time.

A demand schedule is a tabular representation of the total quantity of a particular commodity which a consumer is willing and able to buy at a particular price and a particular time.

Below is an attachment showing the tabular representation and the solution to requirement A

In the first Attachment all that was done was to use the values from the question to get our requirements Total revenue was gotten by (Price * Quantity)

Marginal Revenue was gotten by finding the Change in Total Revenue divided by Change in Quantity

So also a tabular representation of B

All that is required to plot the graph is to match the values gotten to the Y axis which represents revenue and X axis which represents quantity and connect the lines together.

Explanation:

Marignal revenue is the additional revenu generate per unit.

While Total revenue is the total amount (P x Q generated)

of the three mortgage options that demarco and tanya have to choose from, the balloon payment mortgage would be their best option, over adjustable payment and fixed payment plans.ultimately, the balloon payment plan would save demarco and tanya overall, in interest, would cost less monthly, and they would only have to make these payments for 8 years, opposing to 30 years for adjustable or fixed payment plans. 

overall, demarco and tanya would save $80,811 if they chose balloon payments over fixed payments, and would save $116,711 if they choose balloon payments over adjustable payments. benefits with choosing fixed payments over adjustable payments is that, in the end, the payments will still be $836.30 a month, while with adjustable payments, the initial monthly payments will be $763.38 to $1082.70 a month, ultimately leading to a more costly purchase. benefits with choosing fixed payments over balloon payments are not present. benefits in choosing adjustable payments over is that it has a lower interest rate, and starts with lower monthly payments initially. benefits in choosing adjustable payments over balloon payments include a lower interest rate, and lower initial monthly payments. benefits in choosing balloon payments over fixed payments include lower interest rates, lower overall price, lower monthly payments, takes less time to pay off, and does not require a downpayment. benefits in choosing balloon payments over adjustable payments include, lower monthly payments (when averaged), takes less time to pay off, and lower overall price.

hence, option c, balloon payments, is the best option for demarco and tanya to make this purchase, for it will save them a minimum of $80811, and a maximum of $116,711.
