Why is it important that everyone follow the same order of operations when evaluating expressions?

Because if not, different people would get different answers. If the expression is evaluated without using the order of operations, the answer won’t be the same. I hope this helps!

As an example, let’s say we had 3+4x2
Without PEMDAS, we would add 3 and 4, then multiply by 2, getting 14 (the wrong answer).
With PEMDAS, we would multiply 4 and 2, then add 3, getting 11 (the correct answer!).
So if you don’t use PEMDAS, you’ll just get a different answer than you should’ve. Hope that helped!

The Royal Fruit Company produces two types of fruit drinks. The first type is 55% pure fruit juice, and the second type is 80% p

Answer:

First type of fruit drinks: 48 pints

Second type of fruit drinks: 32 pints

Step-by-step explanation:

Let's call A the amount of first type of fruit drinks. 55% pure fruit juice

Let's call B the amount of second type of fruit drinks. 80% pure fruit juice

The resulting mixture should have 65% pure fruit juice and 80 pints.

Then we know that the total amount of mixture will be:

$A + B = 80$

Then the total amount of pure fruit juice in the mixture will be:

$0.55A + 0.8B = 0.65 * 80$

$0.55A + 0.8B = 52$

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.8 and add it to the second equation:

$-0.8A -0.8B = -0.8*80$
