The vector u = (4300, 5200) gives the number of units of two models of laptops produced by a company. The vector v = 1800, 1200 gives the prices (in dollars) of the

two models of laptops, respectively. Identify the vector operation used to increase revenue by 5%.

(the // represent the straight brackets that are used, not division symbols)

A. u⋅(1.05) //v//
B. 1.05(u ⋅ v)
C. 1.05(u + v)
D. 1.05// u⋅v//
E. 1.05 // u // ⋅v

  1. u dot v = revenue
    which is sum of number of each times price of each

    so

    1.05 ( u dot v )
