Question

A fire is burning in a valley. The estimate is that if it burns for h hours, the cost of the lost timber is 1000h dollars. x firefighter can stop the fire in 3600/x hours. The cost for each firefighter is $20(transport) plus $25 per hour
A. let C be the cost of the fire ( cost of firefighters and lost timber). C will depend on both h(time fire burns and x (number of firefighters sent to fight it). Give a formula for C  in terms of x and h

anonymous · Answer

Total Cost = Lost timber  +      fire fighter   ( including transportation)
                  =     $1,00 h     +  $25 * 3,600/ x      +     $20x
