Solve the problem.A marketing company wishes to conduct a $15,000,000 advertising campaign in three media-radio, television, and newspaper. The company wants to spend twice as much money in television advertising as in radio and newspaper advertising combined. Also, the company wants to spend a total of $13,000,000 in radio and television combined. Let x, y and z represent the amount in millions of dollars spent in radio, television, and newspaper respectively. How much should the company spend in each medium? (Express the problem in terms of a system of linear equations and solve it using Gaussian elimination.)
What will be an ideal response?
x = 3, y = 10, z = 2; The company should spend $3,000,000 in radio advertising, $10,000,000 in television advertising, and $2,000,000 in newspaper advertising.
