At the present time, a football player weighs 325 lb. There are 90 days until the player needs to report to spring training at a weight of 290 lb. The player wants to lose weight at a constant rate. That is, the player wants to lose the same amount of weight each day of the 90 days. What weight, to the nearest tenth of a pound, should the player attain in 25 days?

Graphic artists use computer drawing programs, such as Adobe Illustrator, to draw the intermediate frames of an animation. For instance, in the following figure, the artist drew the small green apple on the left and the large ripe apple on the right. The drawing program used interpolation procedures to draw the live apples between the two apples drawn by the artist.
