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…

The figure shows a page with 1-inch margins at the top and the bottom and half-inch side margins. A publishing company is willing to vary the page dimensions subject to the condition that the printed area of the page is 50 square inches. Express the total area of the page, A, as a function of the width of the rectangle containing the print, x.

Ms. Dawson’s call did a science experiment. The class started out with 635 bacteria cells. The growth rate predicted was 5.15%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 23 h from the start of the experiment. Be sure to show your work on how you obtained your second value. Round to the nearest whole number.

Refine your table by calculating values of x that go up in increments of 100 between these two numbers. You can refine even further if you wish. x, number of books sold Income with publisher A, ($) A = Income with publisher B, ($) B = What is your best estimate for the number of books sold that make the plans equal? Use the numerical data above to graphically compare the incomes. Construct a graph to model both publishing plans on the same Cartesian Plane and attach it to this tutorial (you may use Excel or DESMOS if you wish). Which quantity is to plotted on which axis? Properly label and title your graph. What is your best estimate from your graph? Now solve the problem algebraically. You are solving a system of equations by substitution. Part C. Comment on the Process and Interpret the Results Are the solutions you obtained numerically, graphically and algebraically consistent? What factors must the students consider when deciding between these two offers?
