Question 1027228: I have twice as many nickels as pennies and 2/3 as many dimes as nickels. I have at least $3.65. How many of each coin do I have and how much is each coin's amount?

Answer by CubeyThePenguin(3113) About Me  (Show Source):
You can put this solution on YOUR website!
p = number of pennies
n = number of nickels
d = number of dimes

n = 2p
d = 2n/3 = 4p/3
p + 5n + 10d >= 365

Write everything in terms of p.

p + 5(2p) + 10(4p/3) >= 365
73p/3 >= 365
p >= 15

least possible coin amounts: (p, n, d) = (15, 30, 20)
