The least number of bills you could use for any item is using just 5 to pay for the doll.
Step-by-step explanation:

$18 = $10 + $8 = $10 + $5 + $3 = $10 + $5 + $1 + $2 = $10 + $5 + $1 + $1 + $1
Once you have only bill amounts, you can count the number and see how many bills you have to use. Repeat this process for each one.
