There are total 80 dimes in the jar. B/c...
n+d=200 = n=200-d
0.05n+0.1d=$14.00
0.05(200-d)+0.1d=$14.00
10-0.05d+0.1d=$14.00
10+0.05d=$14.00
-10 -10
0.05d=$4.00
0.05d/0.05=$4.00/0.05
d=80
8 hours x $9 = $72
$380/12.5% = $47.50
$72 + $47.50 = $119.50
Eighty million, forty thousand, nine hundred sixty.
