Question

A student wants to buy 4 bottles of lemonade that cost $1.65 each . if they pay with a bill how much will they get back?​

Answer 1

$3.40

Explanation:

"A bill" = "1 bill"

Possibile bills = $1, $5, $10, $20, $50, $100

4 × 1.65 = 6.6

$6.60 is more than $5, but less than $10

Since the student is only using a single bill, it must be the $10 bill

10 - 6.6 = 3.4

$3.40
