Answer:
Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344
Step-by-step explanation:
Selling price of a bottle = $ 0.99
Mark price of of a bottle = 28 % above the selling price
Mark price of of a bottle = 1.28 × 0.99 = $ 1.2672
Now the payment for 20 soda bottles = 20 × mark price of one bottle
The payment for 20 soda bottles = 20 × 1.2672
The payment for 20 soda bottles = $ 25.344
Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344

We can use the distributive property to simplify.
The distributive property is:
![a(b-c)=ab-ac](https://tex.z-dn.net/?f=a%28b-c%29%3Dab-ac)
So, let's simplify the expression:
![\begin{gathered} 2(6-3.2j) \\ =2(6)-2(3.2j) \\ =12-6.4j \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%202%286-3.2j%29%20%5C%5C%20%3D2%286%29-2%283.2j%29%20%5C%5C%20%3D12-6.4j%20%5Cend%7Bgathered%7D)
This is the simplified form.
