PLSS HELP ME WITH THIS!! 20 POINTS!!

Answer:
Each bottle is about $1.45
Step-by-step explanation:
This is because you divide the amount of bottles (19) by the toatl price ($13.11) to get the amount each bottle cost.
Answer:
$0.69 cents
Step-by-step explanation:
To find the cost of one bottle you would have to divide $13.11 (the total price) by 19 (the quantity she got for that price).
[tex]13.11 \19 = 0.69[/tex]
By doing this you will be able to find the price of one bottle; 69 cents
To prove this concept you can multiple the 69 cents by 19 to see if you get back the original price that was given.
[tex]0.69 \times 19 = 13.11[/tex]
