Question 249414: 50% of the coins are pennies. Half of the remaining coins are quarters. The rest of the coins have an equal number of nickles, dimes and half dollars.
We tries assuming 100% so
50 if the coins are pennies.
half the remaining coins (25) are quarters.
leaving 25 coins but you can't divide 25 by 3 equally???
Help!
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
to begin with we don't know how many coins there are total.
We also need to know the total values of the coins.
you can't assume 100 coins
50% doesn't mean 50 pennies
let x= total number of coins
.50x=p
the remaining is also 50%
but half of that is 25%
so 25%are quarters
are equally nickels , dimes and half dollars.
let n=number of nickels
n=d
n=h
So that 3n=.25x
so far then we have
x=p+q+n+d+h
x/2=p
x/4=q
3n=.25x
n+d+h=.25x
3n=n+d+h
x/2+x/4+3n=x
x=12n
I suspect we are missing some info such as a dollar amount for something.
Plus we haven't actually been asked to solve for anything in particular.
