Divots's liquidity is better $/$ worse than its peers in $1999?$

Divot's liquidity has improved $/$ gotten worse in the last year.

What about the long$-$term solvency ratio?

What about the inventory turnover?

Suppose you invest $$500$ today. If your investment pays $6\%$ interest per year, how much will you have at the end of four years?

$(1)$ Suppose you can afford monthly car payments of $$500.$ If you can borrow at $6\%$ for $5$ years, how much can you afford to borrow? Note that monthly compounding is assumed.

$(2)$ If you invested $$1,000$ at the end of every month for $20$ years and it earned $6\%$ per year, compounded monthly, how much would you have after $20$ years?

Please show the work on how each one is calculated!
