Question 51601: Hi,
I'm doing algebra homework and have come to a problem I can't figure out. I have to convert the below word problem into a math problem, and solve it.
I'm not just looking for the answer (I could go to the back of the book for that), I need to know every step of how to get to the answer.
I've tried several 'unconventional' ways of solving it... but nothings worked out.
The problem is:
"Lorraine has $7.70 in dimes and quarters in her car coin carrier for tolls. If the number of quarters is two more than twice the number of dimes, how many of each type does she have?"
Unfortunately, the text book I'm using is a used book, and the ISBN has been covered. However, you can find the textbook at: http://www.prenhall.com/setek/ it's called "Fundamentals of Mathematics"

Question 51663: Hi,

I have to convert the below word problem into a math problem, and solve it.

I tried: "5x + 10(x + 36) + 25(x + 60) = 11860 or 5x + 10x + 360 + 25x + 1500 = 11860 or 40x = 1860" but that didn't work...

The problem is:

"A vending machine contains $118.60 worth of coins. If there are 24 more quarters than dimes and 36 more dimes than nickels, how many of each coin are in the machine?"

Unfortunately, the text book I'm using is a used book, and the ISBN has been covered. However, you can find the textbook at: http://www.prenhall.com/setek/ it's called "Fundamentals of Mathematics"

n=nickels, d=dimes, q=quarters. I set formula as n+d+q=12 and furthered it to .5n+.10d+.25q=$1.00. I wasn,t sure if I need a third formula or if I was right. I did a process of elimination with coins and came up with these combinations: #1 2q,0d,10n #2 1q,4d,7n #3 0q,8d,4n
