Answer:
So the total amount she payed is $40.35 with the change of $2.77.
Explanation:
First you would multiply the price of the item by how many items you are purchasing, like you would multiply $15.35 by 2. Since there are two of that item. Which is $30.7. Same for the next one, but 1/2 is 0.5. So since 1/2 a pound is less than 1 pound you would divide the whole price by half. So 3.18 divided by 2= $1.59. So that answer $1.59. Then for the last one you have one gallon of milk so you multiply that by 5.29. So that answer is $5.29. Finally you add it all up and that is your answer. So the total is $37.58. But then you have to find how much she payed. So you add it all up PLUS the change. So $37.58 + $2.77= $40.35. So the total amount she payed is $40.35 with the change of $2.77.
