Write System
Horatio has 57 coins consisting of nickels, dimes, and quarters. He has twice as many dimes as nickels. If
the coins are worth a total of $7.25, which system of equations is used to determine how many of each coin
Horatio has?
A n+d+q=57
n = 2d
0.05n+ 0.10d+0.25g = 7.25
B. n+d+q=57
n = 2d
5n+ 10d 25g = 7.25
C. n+d+q=57
d=2n
0.05n+0.10d+ 0.25g = 7.25
D. n+d+g 57
d=2n
5n+ 10d 25g = 7.25
