Answer: Part A: 507 ounces Part B: 84.5 cups
Step-by-step explanation: To convert liters to ounces, we need to know that 1 liter is equivalent to approximately 33.8 ounces. Therefore, to find out how many ounces are in 15 liters, we can multiply 15 by 33.8.
15 liters * 33.8 ounces/liter = 507 ounces
Since each coffee cup holds 6 ounces, we can divide the total number of ounces (507) by the capacity of each cup (6) to find out how many cups can be filled:
507 ounces / 6 ounces/cup = 84.5 cups
Since we cannot have a fraction of a cup, we can fill a total of 84 cups with 6 ounces of coffee each.
