Question 1126735: Central Waste Management has a fleet of 35 trucks that are able to haul 173 tons of trash per day. When they increase the number of trucks to 47, they can haul 236 tons of trash per day. When the company contracts to pick up trash for the city of Bellmead, the amount of trash is expected to increase to 253 tons per day. Estimate the number of trucks that will be required. (Round your answer up to the nearest whole number.)

The ratio  "Tons per truck"  is  173%2F35 = 4.94 in the first case.


This ratio is  236%2F47 = 5.02 in the second case.


It is not the rocket science, not a precise Mechanics, not a Nano-technology and not the atomic Physics.


So, with certain confidence we can assume that each truck carries about 5 tons of trash.


Then the number under the question can be  estimated as  253%2F5 = 50.6, or about 51 trucks (rounded up to the nearest whole number).
