Question 1198442: S3.25 in dimes and nickels, were distributed among 45 boys. If each received
one coin, how many received dimes and how many received nickels? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! x = number of dimes
y = number of nickels
x + y = 45
.1x + .05y = 3.25
those are your two equations that need to be solved simultaneously.
multiply both sides of the first equation by .1 and leave the second equation as is to get:
.1x + .1y = 4.50
.1x + .05y = 3.25
subtract the second equation from the first to get:
.05y = 1.25
solve for y to get:
y = 25
this makes x = 20 because x + y = 45
you have:
20 dimes and 25 nickels.
the total value is 20 * .10 + 25 * .05 = 2.00 + 1.25 = 3.25.
your solution is:
20 received 1 dime each and 25 received 1 nickel each.
