- Mai sells makeup online and has noticed that demand for her products, glittery lip gloss, has varied wildly over the past few months she has been selling it. She's been doing some online advertising and thinks there might be a relationship between how much she's spending each week on ads and her weekly lip gloss sales, so she's used Excel to create an Associative Forecast: where the intercept is -20 and the slope is 2.5 per $ spent advertising. Use this information to forecast lip gloss sales in week 18, when she will be spending $100 on advertising. Answer:Sales in a company are $188 million in 2009 and increase $208 million in 2010.
