23 Revenue Pack-Em-In Real Estate is building a new housing development. The more houses it builds, the less people will be willing to pay, because of the crowding and smaller lot sizes. In fact, if it builds 40 houses in this particular develop- ment, it can sell them for $200,000 each, but if it builds 60 houses, it will be able to get only $160,000 each. Obtain a linear demand equation, and hence determine how many houses Pack-Em-In should build to get the largest revenue. What is the largest possible revenue? [HINT: See Example 3.]
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 miles away.
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 experiments to set up the devices.
