Answer and Explanation:
Old equipment=2.5 mins per serving bowl
New equipment=1.5 mins per serving bowl
With old equipment, in one hour Eddy Jones can produce 60/2.5= 24 serving bowls
With new equipment, in one hour Eddy Jones can produce 60/1.5= 40 serving bowls
With old equipment, in 8 hours Eddy Jones can produce 24*8=192 serving bowls
With new equipment, in 8 hours Eddy Jones can produce 40*8=320 serving bowls
Therefore in 8 hours with new equipment Eddy Jones will produce 320-192= 128 more serving bowls than with old equipment.
