Question

Dave has 7 coins. He only has pennies,nickels, and dimes. He has more nickels then pennies and more dime then nickels. How much money does he have?

Answer 1

So let P be the number of pennies, N = number of nickels,
D = # of dimes.

Then P + N + D = 7
and D > N > P

what values can P, N and D have?

Answer 2

This is a thrid grade math sheet so i typed the question as it was worded on the sheet.

Answer 3

x=#pennies
y=#nickels
z=#dimes
x+y+z=7
z>y>x
z=4
y=2
x=1 works
that's 4(0.1)+2(0.05)+1(0.01)=$0.51
