MyLab Finance Dave's employer offers a 401(k) plan, but Dave has not participated in it up to this point. Now he wants to seriously consider contributing. His employer will allow him to invest about $7,000 of his salary per year and match his contribution up to $3,000, for a total contribution of $10,000 per year. The retirement funds will be invested in one or more mutual funds. Dave's best guess is that the retirement fund investments will earn a return of 7% per year.
