Final answer:
Your friend has received a 90% raise with the new job offer.
Step-by-step explanation:
Based on my knowledge of economics, I think your friend has received a significant raise with the new job offer. Here's why:
The current salary of $50,000 and the new salary of $95,000 show a difference of $45,000. This means your friend is getting a raise of $45,000.
The percentage increase in salary can be calculated using the formula: (Increase in salary/original salary) * 100%. In this case, that would be ($45,000/$50,000) × 100% = 90%. Therefore, your friend has received a 90% raise.
