Question

The vector  gives the number of units of two models of laptops produced by a company. The vector  gives the prices (in dollars) of the two models of laptops, respectively. Identify the vector operation used to increase revenue by 5%.

Quizplus · Accepted Answer

To increase revenue by 5%, we need to multiply the prices vector by 1.05. So the correct operation is scalar multiplication. Option A adds a vector (not a scalar) to the original prices, option C subtracts a vector (not a scalar) from the original prices, and options D and E involve different vector operations that do not relate to increasing revenue. Therefore, option B (scalar multiplication of the prices vector by 1.05) is the correct choice.
