Problema Solution
A crowd of 50,000 fans is expected to attend the homecoming football game. If the typical vendor can serve 1,500 customers per hour and the game will last for four hours, how many vendors are needed to ensure that each fan can be served during the game? (Round to the nearest whole number.)
Answer provided by our tutors
Let 'x' represent the number of vendors, x is integer.
In 4 hours each vendor will serve: 1,500*4 = 6,000 customers
In 4 hours x vendors will serve: 6,000x customers
6,000x >= 50,000

x >= 8.33
The smallest integer that is larger than 8.33 is 9 therefor 9 vendors are needed.
