Follow the instructions that follow each image to learn how to write a check with cents. Enter the date on the top right Insert the date in this field. You can write it out pretty much however you want but you must include the month, date and year. Here are some examples of acceptable formats. Math Home Search Dr. Math Switching Dollars and Cents Date: Math - finding an equation Let's say a woman receives a check from the IRS and goes to cash it. The bank teller accidentally switches the dollars and cents, so what was dollars he gives her in cents and vice versa. After she has spent the nickel she has twice the amount of the original IRS check.

How do I find the answer and find a system of equations? I've tried guess and check and still haven't figured it out: Math - finding an equation Let D be the number of dollars, and C the number of cents the check is made out for.

This gives you one equation: There is a hidden condition that you will also need: This happens because amounts of money do not have numbers of cents more than 99 or less than zero.

Are you beginning to see a pattern? I think you can do the rest. Hard word problem Dr. Math, my teacher gave me this word problem for extra credit.

I am having problems with it. A man went into a bank to cash a check. In handing over the money, the teller by mistake gave him dollars for cents and cents for dollars. He pocketed the money without examining it, and spent a nickel on his way home.

He then found that he possessed exactly twice the amount of the check. He had not money in his pocket before going to the bank. What was the exact amount of that check? Thanks for your help, Cody. These answers are no good, but looking at the original equation, if you decrease y by and x by 98, the answer will still obviously work, so do that: Equations like this where whole number answers are required are called "Diophantine equations" in honor of the Greek Diophantus.

They are in general very hard to solve, but linear equations like this one can be solved using exactly the method I showed you above. Of course, you never know how many steps it will take to get to the answer! Is it factored out? If so, then how? In my problem I replaced the five with a 62 throughout and it worked perfectly.

I came about this in a strange way, however. For the actual values of x and y I got and respectively. I subtracted from the y value and 98 from the x value, as was mentioned in one of the examples, and lo and beholdWhen you need to pay for it with a bank check, just make sure you emphasize cents rather than dollars in your amount.

The process is fairly simple.
