Write the equation for figuring out his wages, and then solve it to find out how many hours he worked. Step 1: In order to find out how many hours John works, you first need a formula for calculating his wages:. With inverse proportionality, when one quantity increases the other decreases, and vice versa.

The key to solving this problem is to keep in mind that each person works at the same rate regardless of how many people share the workload.

Using this constant, we can return to the first equation and solve for the time when 8 people are working:. While reading a book Sarah notices that she has read 3 pages after 10 minutes.

If she keeps reading at this rate, how many pages will she have read in 1 hour? The number of pages read is directly proportional to the time spent reading. Rearrange to solve for the constant:. If it takes 9 hours for 4 people to build a shed, how many people are needed to build the same type of shed in one-third of the time?

The constant of proportionality is equal to the product of time and the number of people. Now, this problem asks for the number of people needed to build the second shed. This means we need to find a way to solve for. Use the given values to solve. How long will it take to get there using the freeway going 65mph if the distance is the same?

City route:. Freeway route:. We can set these equations equal to each other, since both are equal to. A father is buying cheeseburgers for his children. How many cheeseburgers did he buy? Let Elena's be equal to :. It takes Suzie 45 minutes to bike to the grocery store.

What is Suzies average speed? Express answer in miles per hour. Plug in the information given in the problem, remembering that the questions says to state the answer in terms of miles per hour, and we are give her time in minutes. Change minutes to hours:. Suzie's rate is. How many ice cream cones can be purchased for? The friends have the bus from PM to AM. One of the teachers at the high school, Mr. Jones, has offered to chip in the rest. If he does, how much will he pay?

All courses.Publisher: Saylor Foundation. The book gives students a good insight about pre-Algebra concepts. I gave is a five because of the breaking down of the problems and the use of the colors to reach the visual learners. There is no glossary, but a table is given. Comprehensiveness rating: 5 see less. Looking at the examples, and exercises given to students for practice, the book is accurate.

I did not find any errors. I cannot say that the book is culturally sensitive. The book is not as diverse as our today classrooms. The longevity of the bool is good.

The topics will be still good many years to come. It won't be a lot of changes. The use of certain symbols like the radical could more clear at times so student will not make mistakes reading them. The book is split in good and easy to read parts. It makes is easy for teachers and students as well. The book is well organized.

There is a linearity in the topics studied and I can see a logical follow up. The only minor point, is a small review before starting the new chapter so the students can rely on the previous chapters for better understanding. There is inconsistencies on the PDF version of the book. The book is using different platform to display content like math symbols which are not clear on the PDF version of the book, It is always better to tell the audience which platform to use for better reading.

I did not see or encounter any grammatical errors even though I did not read every sentence in the book. I did not see any relevance of cultural insensitivity, but looking at the diversity of our classrooms, the book should add some cultural items to help the minority students understand the topics using their cultural background.

The book has a lot of potential to it. There is a need for cultural sensitivity on the mathematical topics, and also raising the bar to help some advance students get a head, and get more challenged. The book is very comprehensive. There is a table of contents but no glossary. The book does not have that much text, which is very good for fast learning and reading.

Additionally the efficient use of text results in short worded problems. The worded problems do not have a great deal of special names of people or places or events, thus they appear to be applicable to many groups and should be pertinent for many years. The book is very clear. Diagrams are simple.
