.
N=number of nickels; P=number of pennies
.
N+P=73
P=73-N
.
$0.01P+$0.05N=$3.25
$0.01(73-N)+$0.05N=$3.25
$0.73-$0.1N+$0.05N=$3.25
$0.04N=$2.52
N=63 ANSWER 1: There are 63 nickels.
P=73-N=73-63=10 ANSWER 2: There are 10 pennies.
.
CHECK:
$0.01P+$0.05N=$3.25
$0.01(10)+$0.05(63)=$3.25
$0.10+$3.15=$3.25
$3.25=$3.25
