Answer:
264 ounces
Step-by-step explanation:
#Convert Xan weight into ounces:
[tex]1lb= 16 \ oz\\\\66\ lb=66\times 16=1056 \ oz\\\\\therefore Xan's=1056 \ oz+ 99 \ oz=1155 \ oz[/tex]
Convert Katie's 88 pounds 11 ounce to ounces:
[tex]1lb= 16 \ oz\\\\88\ lb=88\times 16=1056 \ oz\\\\\therefore Katie's=1408 \ oz+ 11 \ oz=1419\ oz[/tex]
The difference is calculated by subtracting Xan's from Katie's:
[tex]=1419 \ oz-1155 \ oz\\\\=264\ oz[/tex]
Hence, the difference between the weights is 264 ounces
