The number of dimes that Elane has is seven less than three times the number of nickels. Problems involving tickets or stamps are very much like coin problems.

Each type of ticket and stamp has a value, just like each type of coin does.

But this type of problem introduces us to some techniques that will be useful as we move forward in our study of mathematics.

If we have a pile of dimes, how would we determine its value?

In our next example, we have to relate the quantities in a different way. Each ticket was either an adult ticket or a child ticket. To find out, we would follow the same logic we used above.

If he sold 20 child tickets, how many adult tickets did he sell? In each case, we subtracted the number of child tickets from 100 to get the number of adult tickets.

Example \(\Page Index\) Galen sold 810 tickets for his church’s carnival for a total revenue of ,820.

Children’s tickets cost each and adult tickets cost each.

In most of our examples so far, we have been told that one quantity is four more than twice the other, or something similar.

Example \(\Page Index\) Jesse has .02 worth of pennies and nickels in his piggy bank.

The number of nickels is three more than eight times the number of pennies. Represent the number of each type of coin using variables.

In mixture problems, we are often mixing two quantities, such as raisins and nuts, to create a mixture, such as trail mix.

In our tables we will have a row for each item to be mixed as well as one for the final mixture.

  1. Still, you need an introductory paragraph that sets the tone and tells the reader what this story is about. Regardless of the fact that this is a personal narration, it should still have a logical flow. When people read books, they move through the pages easily when they involve conversations. It’s really difficult to edit your own work, since you’re attached to it.
