Answer:
The substitution method consists of solving for in one of the equations, basically the one that is easiest, and substituting the resulting expression in the other. With this, the second equation is converted into a linear equation with one unknown, which is solved by simply solving for.

Yes, they are.
You're not changing anything fundamental about them. They're just flipped expressions.
Answer:
The 16-oz bottle of parmesan cheese is the better buy.
Step-by-step explanation:
Even though 8-oz is half the amount of 16-oz, that doesn't mean it's cheaper. Let's find the amount of and 8-oz bottle when a 16-oz bottle is $5.78:
16-oz bottle of parmesan cheese = $5.78
A price of an 8-oz bottle when 16-oz is divided by 2:
16 ÷ 5.78 = $2.76
The original price of the 8-oz bottle should've been $2.76 but it's more expensive due to VAT.
So the 8-oz bottle is more expensive, therefore the 16-oz bottle is the better buy!
830$ there are 52 weeks in a year. 52 times 15 is 780. 780 plus 50 is 830
