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 10.4B, Problem 7A

a. Mr. Alberto wanted to count the score on a term paper as 60 % of a final grade, homework as 25 % of the grade, and the final exam as the remainder of the grade. A student in the class made 85 on the term paper, had a 78 average on homework, and scored 90 on the final exam. What number could Mr. Alberto use to determine the student’s grade if he used his grading scheme?

b. Write an algebraic expression to generalize the scoring procedure for Mr. Alberto’s class to allow him to use any percentages he likes for the scoring scheme. Clearly describe what the variables represent.
