I have 9 of each coin
STOP TELLING THE ANSWER!
he hi he ho he hi he h0
you would do 9 of each coin
There would be nine of each coin.
Nickles: 9 x 5 = 45
Dimes: 9 x 10 = 90
Pennies: 9 x 1 = 9
45+90+9= 144
9 coins each
9.dimes=90
2.nickels=10
44.pennies=44
=1.44
Let x be the number of pennies. Then we also have x nickels and x dimes.
1x + 5x + 10x = 144
=> 16x = 144
=> x = 144/16 = 9
all of them are 9
