Question

Looking for some assistance:

Express the situation as a system of two equations in two variables. Be sure to state clearly the meaning of your x- and y-variables. Solve the system by row-reducing the corresponding augmented matrix. State your final answer in terms of the original question. For the final days before the election, the campaign manager has a total of $39,000 to spend on TV and radio campaign advertisements. Each TV ad costs $3000 and is seen by 10,000 voters, while each radio ad costs $500 and is heard by 2000 voters. Ignoring repeated exposures to the same voter, how many TV and radio ads will contact 140,000 voters using the allocated funds?

x = _____________ TV ADS

y= _____________ RADIO ADS

Explanation / Answer

3000*x + 500*y = 39000

where x is number of TV ADS

and y is number of RADIO ADS

10000 * x + 2000 * y = 140000

solving above two equation

x = 8 TV ADS

y = 30 RADIO ADS
