Well 63 divide by 9 is 7 but 9 divide by 63 is .14
Answer: 80
Step-by-step explanation:
No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.
But if we just took off 30% from 100 originally, you would be at $70.00
So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.

For

the derivative is negative.
For

the derivative is positive.
Therefore at

there's a minimum.
