method 2 should be selected

Explanation:

The computation is shown below:

For Method 1

Value = $740,000 + $190,000 ÷ 1.14 + $190,000 ÷ 1.14^2 + $190,000 ÷ 1.14^3 - $135,000 ÷ 1.14^3

= $1,089,988.93

For Method 2

Value = $870,000 + $135,000 ÷ 1.14 + $135,000 ÷ 1.14^2 + $135,000 ÷ 1.14^3 - $170,000 × 1.37 ÷ 1.14^3

= $1,026,219.458

As we can see that in the method 2 there is a less cost as compared with method 1

So, method 2 should be selected
