Problema Solution
6 skilled workers were able to make 150 shirts in 5 days. How many more workers must be hired to make 200 shirts in 4 days?
Answer provided by our tutors
assuming the new workers are skilled...
shirts per day per worker:
150/(6*5)
let 'x' represent the number of workers hired, then 'x+6' represents the number of workers:
150/(6*5) = 200/((6+x)*4)
solving for 'x' we have x=4
4 new workers must be hired
