The first 50% of the road is completed in $250,000. After the rest is completed the total amount used is $550,000. This means the second half required 550,000 - 250,000 = $300,000.
The extra amount required for the second half was 300,000 - 250,000 = 50,000.
Or in terms of a percentage of the amount required for the first half is ir 50,000/250,000* 100 = 20%
The second half of the road cost 20% more to construct that the first half.
The total cost is 550,000
The cost of the first 50% = 250,000
Then the cost of the second 50% = 550,000 - 250,000 = 300,000
Now we need to calculate the difference between both halves.
==> The second half costs 50,000 more than the first half.
Now we need to calculate the percent of the extra cost.
==> 50,000 / 250,000 = 0.2
==> 0.2 * 100 % = 20%
Then the second half costs 20% more than the first half of the project.
