a prominent local politician for lusaka central constituency,and as his campaign manager, you need to decide how to promote the candidate. there are three ways you can you can do so: you can send glossy, full-color flyers to registered voters of the constituency,you can also run a political commercial during the main news on znbc television, and /or you can buy a full- page ad in the post newspaper .
you are reliably informed that 250,000 registered voters live in ludaka central constituency, and 36 percent of them read newspaper. 50,000 voters watch the main news on znbc television, and 30 percent of them also read newspapers. you also know that the television commercials would cost k40,000, the newspaper ads k27,000, and the flyers mailed to voters k0.9 each , including printing and bulk rate postage.
suppose that the success of the candidate depend on your campaign reaching at least 125000 voters and that , because your budget is limited , you can must achieve this goal by a minimum cost. what would be your plan and cost of that plan?
I started answering as follows
0.36*250000= 90000 read newspapers but don't watch tv.
50000 watch the main news tv but
0.30*50000= 15000 both watch tv and read newspapers.
voters reached by newspaper only are 90000 this gives us the total cost of k27000
then those reached by tv only are 50000 and the total cost is k40000.
those reached by flyers mailed to voters are 125000 and the cost is 125000*0.9= 112500.
from here I need to make a plan, explain the plan and its cost, am I on the right path? if what I have above is correct then help with plan and its cost.
please help me....
