$=26.7\times \frac{0.83276…}{0.43}+\frac{3000}{(1+0.43)^{5}}$
Add the numbers: $ 1+0.43=1.43$$=26.7\times \frac{0.83276…}{0.43}+\frac{3000}{1.43^{5}}$
$26.7\times \frac{0.83276…}{0.43}=51.70907…$$=51.70907…$
$\frac{3000}{1.43^{5}}=501.69649…$$=51.70907…+501.69649…$
Add the numbers: $ 51.70907…+501.69649…=553.40556…$$=553.40556…$
