For the following problem, identify the slope or rate of change and describe it in terms of the problem:
sally owns a small strawberry patch in her back yard. she estimates she has 1, 600 strawberries at noon before customers arrive to pick their own berries from her yard. at three o'clock that afternoon she knows twenty customers have purchased berries, and she has sold a total of 50 full baskets. she estimates she as only 100 strawberries left in the patch. she then makes several graphs using that data, with time along the x-axis. given this information select the statement below that is false:

a. customers are picking and buying about two and a half baskets each.
b. a slope of 20/3 is an estimate of how many customers are in the field per hour.
c. she is selling 1, 600/3 or an estimated 533 strawberries per hour.
d. a slope of 30/1 is an estimate of how many strawberries are in each full basket.
