Michael opens a store selling specialty artisan breads. before he can begin baking and selling bread, he purchases a bread oven. each week he sells the same number of loaves and earns the same amount of money. write an equation to show how much money he has earned at any week. x y week profit in dollars 1 –250 2 –170 3 –90 4 –10 5 70 a. y = 80x + 70 b. y = 80x – 330 c. y = 80x – 250 d. y = 80x

1.5x + 0.2y = 2.68 1.6x +0.3y = 2.98 which statement describes the graph of the system of equations

The library sells 376 books at its annual used-book sale. the sale takes in a total of $2119. children's books cost $4, and adult books cost $7. let x = number of children's books sold, and let y = the number of adult books sold. which system of equations can the librarians use to model this situation?
