Official Explanation

The construction budget for the urban site is 40% of c, the construction budget for the rural site. The operating budget for the urban site is 135% of b, the operating budget for the rural site, and b is a maximum of $480,000. If the maximum total budgets are equal, 0.4c + 1.35b = c + b.

Simplifying 0.4c + 1.35b = c + b gives you 0.35b = 0.6c. The maximum value of b is $480,000, so 0.35 × $480,000 = 0.6c, and c = (0.35 × $480,000)/0.6 = $280,000.

If $200,000 is shifted from labor to construction, b = $280,000, and c = $480,000. The urban budget becomes 0.4c + 1.35b = 0.4($480.000) + 1.35($280,000) = $570,000. The original budget was 0.4($280,000) + 1.35($480,000) = $760,000, so the change is $760,000 – $570,00 = $190,000.

"The urban location will require only renovation, which would cost 40% less than building the rural location" -> Doesn't that make: renovation_urban=0.6*constuction_rural ??

i still have issue. if we take in financial terms operating cost is only for labour, not to the construction. Earlier i took 480,000 as sum of both construction and labour. Now, when i reread the question i understood it is only labour. Then how we equate construction and lavour cost to 480,000.Please help me.
