a company has recently been hiring new employees. today the company has 26% more employees than it did a year ago. if there are currently 69300 employees, how many employees did the company have a year ago

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

Need solving this second acceleration problem.

Collin did the work to see if 10 is a solution to the equation r/4=2.4
