Can you help me with this question? With solution. Thankyou

Using the given formula of A=P(1+r/n) . What is the value of an investment of $3,500 after 2 years if it earns 1.5% compounded quarterly?

A mechanical contractor is trying to calculate the present worth of personnel salaries over the next five years. He has four employees whose combined salaries thru the end of this year are $150,000. If he expects to give each employee a raise of 5% each year, the present worth of his employees' salaries at an interest rate of 12% per year is nearest to? Formula: P = A (1 - (1 + g / 1 + i)) / ( g - i)
