Since Meena hasn't advertised very heavily (she currently pays $300 a month for advertising on Google and $150 a month for a small spot in the local paper), Keon is thinking of adding some more aggressive marketing. He believes that paying for a trio of large billboards around the city could boost annual sales by 25% (with proportional increases in vehicle costs). Each billboard would have an initial cost of $1,000, followed by $500 monthly. Keon is also thinking of expanding from Google to social media. He estimates that if he spends $1,000 a month on social media, he would be able to increase limo rental prices by 10% and not suffer any drop in sales volume. However, Keon wants to make sure that his advertising strategy is ethical and tasteful. He is looking for advice on the best marketing strategy given his industry and his limited budget. pls explanation give recommendation with calculations
