A)y=-15x+145 B)See below C)8 days

Work Step by Step

A)There are 145 pounds of food, to begin with. There are 15 pounds eaten per day so it decreases. The equation would be y=-15x+145. B)To graph go to the first point (0,15) and move down 15 and over 1 to the right. Plot the 2nd point and connect them with a line. C)If y=35 find X: 35=-15x+145 -subtract 145 from both sides- -120=-15x -divide both sides by -15- 8=x In 8 days, there would be 35 pounds of food.
