Tim Smith applied for a loan for a new engine on his van for his pool cleaning business. In order to get the loan, he needs to know what his rate of change in profits is and how fast his profits are changing. He gets 33 clients normally a year, he just recently started getting 2 more clients a year. Each client pays $883.14, and there has also been a recent decline in his profits, a decrease of $10.98 per client. What is the rate of change in his profits, and how fast are the profits changing?
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.
