Is there multiple choice answers? If so I would love to help.
Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
<span>Let x=0.8888...
x=0.8888 Start with the given equation
10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right)
Now subtract the equation x=0.8888 from 10x=8.8888 to get
10x-x=8.8888-0.8888
9x=8 Combine like terms. Notice how the decimal portions cancel out.
x=8/9 Divide both sides by 9 to isolate x
So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)</span>

Answer:
491 mg per dose
Step-by-step explanation:
1 kg ≈ 2.2 lbs
81/2.2 36.82 kg
40*36.82 ≈ 1472.8 mg/day
1472.8/3 ≈ 490.93
to the nearest mg = 491 mg per dose
