Answer:
To determine the number of water bottles Kathryn needs to drink, we'll follow these steps:
1. Calculate the total amount of water Kathryn needs to drink:
- The doctor advised Kathryn to drink half her body weight in ounces of water.
- Kathryn weighs 121.5 pounds.
- To convert her weight to ounces, we can multiply it by 16 since there are 16 ounces in a pound.
- Therefore, Kathryn weighs 121.5 pounds × 16 ounces/pound = 1944 ounces.
- Half of her body weight in ounces is 1944 ounces ÷ 2 = 972 ounces.
2. Determine the number of water bottles Kathryn needs to drink:
- Each water bottle contains 20.25 ounces.
- To find the number of water bottles needed, divide the total amount of water Kathryn needs to drink by the amount in each bottle.
- Therefore, Kathryn needs to drink 972 ounces ÷ 20.25 ounces/bottle = 48 bottles.
Based on the calculations, Kathryn will need to drink 48 water bottles to meet the doctor's recommendation of consuming half her body weight in ounces of water.
