The profit earned on the sale of tool sets can be represented as the product of the number of tool sets sold and the difference between the selling price and the cost of making each set. The selling price of each tool set is $19.95, and the cost of making each set is $4.37. Which equation represents p, the profit, in terms of s, the number of tool sets sold? A. p = s(19.95 − 4.37) B. p = s(19.95 + 4.37) C. p = 19.95 + 4.37s D. p = 19.95s − 4.37 Problem #42 Obj 1 - TAKS 2006 11th [A.B1(C)]
