put this solution on YOUR website!Hi, Hope I can help,
.
I have no idea how to set up this problem! Once the equation is set up i know how to solve it. Do you have any suggestions concerning word problems?
.
HERE'S THE EQUATION...
A coin purse contains an equal number of nickels, dimes and quarters. The total amount of money in the purse is 680 cents. How many nickels are in the coin purse?
.
This is how you set it up, since there are an equal number of each coin, we really only have one variable "x"(number of each coin
.
It tells us the value in the purse, we have to know the value of each coin(25 cents = quarter, 10 cents = dime, 5 cents = nickels)
.
To find the value of each coin that is in the purse, we multiply the value of the coin, by the number of coins(examples: five quarters will have a value of
=
=
cents, seven nickels will have a value of
=
=
cents)
.
In our case, the values of each coin are
.
Quarters =
=
=
.
Dimes =
=
=
.
Nickels =
=
=
.
If we add all of our values(25x,10x,5x) together, it will come up with a total value of 680 cents
.
Our equation =
, now we can solve for "x"
.
=
, to get "x" we will divide each side by "40"
.
=
=
.
There are 17, of each coin,
.
you can check by replacing "x" with "17" in our equation
.
=
=
=
( True )
.
your answer is
.
