# How do you find the percent increase from 42 acres to 75 acres?

Oct 30, 2016

78.6% increase

#### Explanation:

Percentage loss, profit, increase, decrease, discount or mark-up are all calculated in exactly the same way:

%" change" = ("change")/("original") xx 100%

The change from 42 acres to 75 acres is $75 - 42 = 33$

The percent change =  33/42 xx 100%

= 78.57%

Note that: xx 100% is the same as $\times \frac{100}{100} \text{ or } \times 1$

The $\times 100$ is used in the calculation, but the % sign is carried down to the answer.
