1.Based on the equation Y = 4.29 + 143.3X, Sales(Y) is in Units of \$1000.00 and Advertising(X) is in Units of \$100. What are Sales when \$2,140.00 is spent on advertising?

2. Sales(Y) is in Units of \$1000.00 and Advertising(X) is in Units of \$100. If we want to calculate the value of sales when \$40,614.00 is spent on advertising. What do we use for X in the following equation?  Y=42.9+143.3X.

Please, do the two questions and show processes

1. In equation Y = 4.29 + 143.3X, Y is in units of \$ 1000.00 means total sales amount is in thousands (for example \$ 1000 is in units of \$1000 we have to right it as \$1). So, in this question Sales (y) is calculated as follows:

Y = 4.29 + 143.3 (21.4) ( since from Advertisement Cost in \$ 100 Units = \$2140 / \$100 = 21.4)

Y = 4.29 + 3066.62 = 3070.91

Sales = \$3070.91 (in \$1000 Units)

2. Sales(Y) is in Units of \$1000.00 and Advertising(X) is in Units of \$100. If we want to calculate the value of sales when \$40,614.00 is spent on advertising, we have to use \$406.14 in the place of X because we have convert the absolute amount in to \$100 units amount (i.e., \$40614 / \$100 = \$406.14).

Hence the Sales (Y)= 4.29 + 143.3 (406.14) = 58204.152 (in \$1000 Units)
