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…

Chapter 9.4, Problem 55ES

Railing Sales. Fireside Castings finds that the total revenue R from the sale of x units of railing is given by the function

R ( x ) = 100 x + x 2 .

Fireside also finds that the total cost C of producing x units of the same product is given by the function

C ( x ) = 80 x + 1500.

A break-even point is a value of x for which total revenue is the same as total cost; that R ( x ) = C ( x ) . How many units must be sold in break even?
