The vector u = (2500, 4900) gives the number of units of two models of laptops produced by a company. The vector v = (1700, 1450) gives the prices (in dollars) of the two models of laptops, respectively. Use dot products to determine the revenue for these two laptops if the price of each is increased by 4%.
A. $11,657,800
B. $11,525,000
C. $11,809,200
D. $11,667,100

Best ResponseYou've already chosen the best response.0I guess you should multiply vector v by 1.04 and then dot product it

Best ResponseYou've already chosen the best response.0wait do I have to dot product it and then multiply it how do I multiply it with just v?
