Systems of
Equations

What are systems of
equations?

How does it apply o real
life?

01

Investing

Many investors rely heavily
on analyzing different stocks
and models to help them
predict possible
profits/losses.

Loans

As a consumer, we frequently
seek loans to help build credit
or simply to help fund a large
purchase we plan to payback.
However as a wise consumer,
it is better to seek various
possible loan offers and
analyze which loan will be less
interest, how long the loan
note is for.

Let's check possible scenarios:

(3 beetle juice, 2 potion punch)

$$2.50j+\ 3.00p=\text{14}$$

(2 beetle juice, 3 potion punch)

There are 2 answers

• (3 beetle juice, 2 potion punch)

  True

• (2 beetle juice, 3 potion punch)

  True

• (3 beetle juice, 2 potion punch)

  False

• (2 beetle juice, 3 potion punch)

  False

​There are 2 ways to do this!!

**visually and/or through calculator.

Open Ended

What way was easiest for you to find the equation? $$y=mx+b$$

​Now solve for y and tell me the solution set?

Confused? I am getting there. I got this!
