You can put this solution on YOUR website!
Let n = no. of nickels
Let d = no. of dimes
:
Write an equation for each statement:
:
"Jose has one-third as many nickels as dimes,
n = 1%2F3d
we can also write this as, (get rid of those annoying fractions)
d = 3n
:
"he has a total of 2.45,"
.05n + .10d = 2.45
Replace d with 3n
.05n + .10(3n) = 2.45
.05n + .30n = 2.45
.35n = 2.45
n = 2.45%2F.35
n = 7 nickels
:
You can find the number of dimes, check your solutions in the first equation
