6(a) A manufacturing company requires 3 hours of direct labour to process every #87.00 worth of raw materials. If the company uses #30,4550.00 worth of raw materials, what amount should it budget for direct labour at #18.25 per hour?
Model answer
Rate = #87.00/3 = #29.00 per hour. At the #29.00/hr rate, the raw materials level implies a certain number of labour hours; converting to the new rate of #18.25/hr: Budget = (304550 x 18.25)/29 = #191,656.47.
