Watch Video on Coin Word Problems – Algebra Help
Access full lesson containing this video at: http://www.yourteacher.com/algebra1/coinproblems.php Students learn to solve “value” word problems, such as the following. Martin has a total of 19 nickels and dimes worth $1.65. How many of each type of coin does he have? Note that this problem requires a chart to organize the information. The chart is based on the total value formula, which states that the number of coins times the value of each coin = the total value. The chart is then used to set up the equation.

Let x = amount of …
Let x = amount of nickels
Let 19-x = amount of dimes
There are a total of 19 coins, rights?
Now since there are 19 coins, you are just trying to solve using one variable. In this case, lets just solve for a number of nickels. If you have x = amount of nickels and 19-x = amount of dimes, you are basically reduce the amount of nickels in the total amount of coins that you have. What ever you have left is the amount of dimes. Got it?

You can easily do …
You can easily do this in your head. Divisions and multiples of 5 always end in 5. So 16 dimes equals 1.60 cents and you need only one nickel to have your ending number of 5 in your answer. Your equation is totally bogus. 14 dimes equals 1.40 cents and 4 nickels equals .20 cents. That’s a dollar and sixty cents. I figured this one out before you even started writing your solution…which didn’t equal $1.65…..duh.
