Answer
# Explanation:
## Step1: Calculate the change amount
$100 - 74.35=25.65$
## Step2: Analyze option A
$2\times10 + 5\times1+6\times0.1 + 5\times0.01=20 + 5+0.6 + 0.05 = 25.65$, number of bills and coins: $2 + 5+6 + 5=18$
## Step3: Analyze option B
$20+5 + 3\times0.25=20 + 5+0.75 = 25.75\neq25.65$
## Step4: Analyze option C
$20+5+2\times0.25+0.1 + 0.05=20 + 5+0.5+0.1 + 0.05 = 25.65$, number of bills and coins: $1+1 + 2+1+1 = 6$
## Step5: Analyze option D
$20+5+6\times0.1+0.05=20 + 5+0.6+0.05 = 25.65$, number of bills and coins: $1+1+6 + 1=9$
# Answer:
C. A $20 bill, a $5 bill, 2 quarters, 1 dime, 1 nickel
