While discount rates are at $10\%$ for every maturity, you evaluate $2$ investment projects with the following cash flows:

Year A B

$0-1,000-600$

$1700400$

$2900600$

$(1)$ Project A has an IRR of $36\%,$ while project B has an IRR of $39\%.$ Suppose you have a budget of $$2,000$ and you can take any project multiple times, which project$($s$)$ should be included in your proposal?
