Projects SS and LL have the following cash flows:

End$-$o f$-$Year Cash Flows:

$0123$

SS $-700490210200$

LL $-600120230500$

If the cost of capital is $10\%,$ then what is the difference NPV$\_$LL $-$ NPV$\_$SS$?$ That is$,$ calculate the NPV for each project and subtract SS$\text{'}$s NPV from LL$\text{'}$s$.$
