p+5n+10d = 94

n=2d

d=n/2

p=2n-2


4 dimes

8 nickels

14 pennies


14+5(8)+10(4) =

14+40+40 = 94

Raymond: Your Equations #2,3,4 represent quantities of coins. Your equation#1 more accurately should be written as “.01p+.05n+.10d=.94” or “p+5n+10d=94” as it represents a dollar value using the quantities of coins.
