Last month, Lloyd's Systems analyzed the project whose cash flows are shown below. However, before the decision to accept or reject the project, interest rates changed and therefore the firm's WACC increased from $4\%$ to $5\%.$ Given the change below in WACC, by how much did the change in the WACC affect the project's IRR?

CF$0=-$$$1,200$

CF$1=$ $$350$

CF$2=$ $$450$

CF$3=$ $$550$

Question $6$ options:

$5\mathrm{.}47\%$

$3\mathrm{.}89\%$

$2\mathrm{.}57\%$

$1\mathrm{.}57\%$

$0\mathrm{.}00\%$
