Question Solved1 Answer Brand Z's annual sales are affected by the sales of related products X and Y as follows: Each $1 million increase in sales of Brand X causes a $2.1 million decline in sales of Brand Z, whereas each $1 million increase in sales of Brand Y results in an increase of $0.1 million in sales of Brand Z. Currently, Brands X, Y, and Z are each selling $6 million per year. Model the sales of Brand Z using a linear function. (Let z = annual sales of Z (in millions of dollars), x = annual sales of X (in millions of dollars), and y = annual sales of Y (in millions of dollars).) z = 11. 1-76.56 Points DETAILS WANITA NOTES wwwww mat. *
