Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Textbook Question

Chapter 8.1, Problem 38E

REVENUE FUNCTION FOR ELECTRIC CARS Bell Motors manufactures two models of electric cars. The demand equations giving the relationship between the unit price, p and q. and the number of cars demanded per year, x and y, of Models S1 and S2 are

p = 60,000 – 4x − 2y and q = 50,000 – 2x − 4y

respectively.

a. What is the total yearly revenue function R(x, y)?
b. What is the domain of R? Sketch the domain R.
c. Is the point (3000, 2000) in the domain of R? Interpret your result.
Hint: Show that x = 3000 and y = 2000 satisfy the system of inequalities obtained in part (b).
d. What is the total revenue realized by Bell Motors if it sells 3000 Model Sis and 2000 Model S2s?
