Answer 2

C (x) = 4x^2 - 296 x + 85; where c = cost

Using the formula that is x = - b / (2a), the axis of symmetry is given below;

According to the above formula, the equation is

a = 4; b = - 296

x = - (- 296) / (2 * 4)

x = + 296/ 8

x = 37

Therefore, Bob should repair 37 watches for having lowest cost.
