b) don earned $120,000 last year and this year he earns $125,000. what was his percentage increase in salary (rounded to 2 decimal places)?
Answer
Explanation:
Step1: Find the amount of increase
$125000 - 120000=5000$
Step2: Calculate the percentage increase
The formula for percentage increase is $\frac{\text{increase}}{\text{original amount}}\times 100%$. So, $\frac{5000}{120000}\times 100%=\frac{500000}{120000}% \approx 4.17%$
Answer:
$4.17%$
