Answer:
I diminished the amount that
Step-by-step explanation:
<span>Let's do this step by step, we know that the guy steals $ 100
So it would be - $ 100 for the store.
The men buy $ 70 merchandise WITH THE MONEY THAT HE STOLE, but the money that he stole CAME BACK to the store
So up to this poin, : - $ 100 + $100 - $ 70 = - $ 70 for the store
After that , the store give $ 30 cash back,
So in the and : - $ 70 - $30 = - $ 100 lost for the store

Let's solve the next equation:

We need to find the value for c, this value is correct when we replaced it with a number and the equality equation becomes true.
First, subtract both sides by 6


Now, subtract both sides by 8


Replacing the c value to verify:


The c value is correct.
The m in the equation is the slope and the y-intercept is the b.
y=1x-1
y=mx+b
