If the original quantity is 10 and the new quantity is 11, what is the percent crease?

10% increase

Step-by-step explanation:

THe original quantity is 10

The new quantity is 11

We need to find the percentage increase.

Percentage increase is found by finding the increase (New - Old) and dividing the answer by the old value (original value). Then we multiply by 100 to get the percentage.

The change is:  11 - 10 = 1

Now, dividing by old, we get:  1/10

Now, multiplying by 100, we get the percentage:  (1/10) * 100 = 10%

So, from 10 to 11, there is a 10% increase

the answer is c. 23/3

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
