A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments. Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250? f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0 f(n) = 250 − f(n − 1) ⋅ 0.4 + 48, n > 0 f(n) = f(n − 1) ⋅ 0.4 + 48, n > 0 f(n) = 250 − f(n − 1) ⋅ 0.6 + 48, n > 0

Robert plans to make a box-and-whisker plot of the following set of data. 27, 14, 46, 38, 32, 18, 21 find the lower quartile, the median, and the upper quartile of the set? lower quartile: 19.5; median: 29.5; upper quartile: 42 lower quartile: 14; median: 27; upper quartile: 46 lower quartile: 18; median: 27; upper quartile: 38 lower quartile: 16; median: 29.5; upper quartile: 42
