A company plans to place advertisements in two different magazines, A and B. A #total budget of $250,000 has been established for these advertisements over the 'coming year, and the company does not wish to spend less than $100,000 of the budgeted amount. Magazine A gives 1,500,000 effective exposures with each use, and costs $7000. Magazine B gives 800,000 effective exposures with each use, and costs $3000. Magazine A is a weekly publication, while magazine B is published monthly. State this problem as a linear-programming problem, and solve it to find the optimal number of advertisements to be placed in magazines A and B in the coming year.
