Question

Nate receives a raise in his salary. His manager uses the expression 1.025s to represent his new salary, where s represents his current salary. What is the percent of increase in Nate’s salary?

Answer 1

Answer:

2.5%

Step-by-step explanation:

Percent increase is found by the formula:

Percent increase = $\frac{new-old}{old}*100$

Where,

• $new$ is Nate's new salary
• $old$ is Nate's old salary

Given old salary is $s$ and new salary as $1.025s$, substituting in the formula gives us:

$\frac{1.025s-s}{s}*100\\=\frac{0.025s}{s}*100\\=0.025*100\\=2.5$

Thus, percent of increase in Nate's salary is 2.5%
