.
Combining like terms on the right side, we have 
.
Finally, dividing by

.
We note that 
and 
, so 
.
So, 
and we're done!
The two sizes chosen for this item are a quart and one gallon.
The first one is advantageous because when it is desired that this be brought some place, it will not be very bulky and not heavy because among the given, this is the smallest. Also, one gallon can be chosen because it does serve many people at a relatively lower price than the other given.
First method:
What we can do first is to distribute directly 4.2 to 6 and
0.43, that is:
4.2 (6 + 0.43)
= 4.2 * 6 + 4.2 * 0.43
= 25.2 + 1.806
= 27.006
Second method:
We can add the two numbers 6 and 0.43 then multiply with
4.2, that is:
4.2 (6 + 0.43)
= 4.2 (6.43)
= 27.006
What we see is the Distributive Property of multiplication
which states that multiplying the sum of a number is similar to multiplying
each number and then adding the products.
