MA1 Cost Classification

The valuation department of a large firm of surveyors wishes to develop a method of predicting its total costs in a period. In a period when the firm undertook 420 valuations, the total costs were £82,200 and in a period when the firm undertook 515 valuations, the total costs were £90,275. The total costs for a period could therefore be represented by

• 41,350+(95 x number of valuations in the period)

• 46,500−(85 × number of valuations in the period)

• 42,300−(95 × number of valuations in the period)

• 46,500+(85 x number of valuations in the period)
