To find the amount of added sugars Luke could eat in a year while keeping it at 9% of his total food intake, we can use the following steps:
- Calculate 9% of his total food intake (1,500 lb): \[ \text{Added sugars} = 1,500 , \text{lb} \times 0.09 \]
- Performing the calculation: \[ \text{Added sugars} = 1,500 , \text{lb} \times 0.09 = 135 , \text{lb} \]
So, Luke could eat 135 pounds of added sugar in a year while keeping it at 9% of his total intake.
