Question

What is the percent increase if your salary went from $85 to $100 per week? Round your answer to the nearest percent, if necessary.

Answer 1

Answer:

Percent increase = 18%

Step-by-step explanation:

To find increase in percentage we apply below formula

$Increase \ percentage = \frac{new \ value - initial \ value}{initial \ value}$

Initial value = 85

new value = 100

$Increase \ percentage = \frac{100 - 85}{85}$

= $\frac{15}{85}=0.176470588$

To get percentage we multiply by 100

0.176470588 * 100 = 17.6470588

So percent increase is approximately 18%

Answer 2

% increase  = 100 - 85
                        ---------     *  100
                          85

                  =   17.65 
                  = 18 % to nearest per cent
