Answer:
61.9% decrease.
Step-by-step explanation:
He was initially drinking 126 ounces of sweet tea
He went to drinking 48 ounces of the sweet tea
The decrease in the intake is 126 ounces - 48 ounces = 78 ounces
Percentage decrease = decrease/original number of ounces × 100
Percentage decrease = 78/126 × 100 = 61.9% (rounded up to nearest tenth)
