Eric weiss, marketing director for charter power and light, is about to begin an advertising campaign promoting energy conservation. each tv ad costs $10,000 while each newspaper ad costs$4,000. weiss has sent the following goals, each in rank order: rank 1: the total advertising budget of $240,000 should not be exceeded
rank 2: there should be at least 10 tv ads and at least 20 newspaper ads
rank 3: the total number of people reached by the ads should be at least 9 million
each television spot reaches approximately 300,000 people. a newspaper advertisement is read by about 150,000 people. set up and solve this goal programming problem to find out how many of each type of ad weiss should place

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
