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 E. $11,639,200

I guess you should multiply vector v by 1.04 and then dot product it

Do 1.04 x 1700 and 1.04 x 1450, this will give you the new price range

Then replace the new values of vector v and times v and u with dot product
