I don't understand this at all TwT

$30

Step-by-step explanation:

since there is no sales tax,

Amount of money used to pay

= change + total price of items bought

Let's find the total price of the items she bought.

Chicken

1 package $12.36

2 packages 2($12.36)= $24.72

Broccoli

1 pound $1.98

½ pound $1.98 ÷2= $0.99

Milk

1 gallon $3.49

Total amount paid

= $24.72 +$0.99 +$3.49

= $29.20

Thus, amount of money Susan used to pay

= $29.20 +$0.80

= $30
