Question 1190833
<font color=black size=3>
x = number of pennies
x = number of nickels
x = number of dimes
For each coin type, x is the same number


1x = value from the pennies
5x = value from the nickels
10x = value from the dimes
values are in cents


1x+5x+10x = 16x = total value
Set this equal to 144 cents ($1.44) and solve for x


16x = 144
x = 144/16
x = 9
<font color=red>The wallet has 9 pennies, 9 nickels, and 9 dimes</font>


A = 9 pennies = 9 cents
B = 9 nickels = 9*5 = 45 cents
C = 9 dimes = 9*10 = 90 cents
A+B+C = 9+45+90 = 144 cents = 144/100 = $1.44


The answers are confirmed.
