The manager of a snack bar buys bottled water in packs of 35 and candy bars in packs of 20. Then, she sells the items individually. Yesterday, she bought the same number of water bottles as candy bars to sell at the snack bar. If she bought the lowest number of items possible, how many packs of each item did she buy?
Answer
A
5 packs of bottled water and 5 packs of candy bars
B
4 packs of bottled water and 7 packs of candy bars
C
8 packs of bottled water and 14 packs of candy bars
D
20 packs of bottled water and 35 packs of candy bars
Explanation
The number of items must be a common multiple of 35 and 20. The smallest such number is 140, since 35 × 4 = 140 and 20 × 7 = 140. So she bought 4 packs of bottled water and 7 packs of candy bars, which is choice B.
