8%=0.08 and 100%=1 (100% represents the original weight in percentaje)
If x is the weight you can express: 1x-0.08x=15.1
solve for x: 0.92x=15.1
x= 15.1/0.92=16.1
The original weight was 16.41 ounces
1 thousand a month would be my guess
Use the Pythagorean theorem
Side = sqrt(8^2 - 6^2)
Side = sqrt(64-36)
Side = sqrt(28)
Side = 5.29
Rounded to nearest tenth = 5.3
