A movie theater observes that on Saturdays, the number of soda cups it has decreases by about 15 of the initial value every hour. Each Saturday morning, the movie theater stocks 1250 cups. Rosalia and Monica work at the movie theater this Saturday. Monica says that there will be 1000 cups left after 4 hours because 1250(15)⋅4=1000. Rosalia says this is not right and that there will be 250 cups left after 4 hours. Which of the following statements are true? A. Monica is correct. The equation 1250(15)⋅4=12505⋅4=250⋅4=1000 gives the correct number of cups left after 4 hours.
B. Monica is correct. After the first hour, there will be 1188 cups left. After the second hour, there will be 1125 cups left. If you continue, there will be only 1000 cups left after 4 hours.
C. Rosalia is correct. The equation f(x)=1250−250x gives the correct number of cups left after x hours.
D. Rosalia is correct. After the first hour, there will be 1000 cups left. After the second hour, there will be 750 cups left. If you continue, there will be only 250 cups left after 4 hours.
