QuestionExpress the RDI of a supplement ($800 \mathrm{mg}$) with a variation of $\pm 80 \mathrm{mg}$ using an absolute value inequality. Solve it.

Studdy Solution
Combine the results of the two cases to find the range of values for x.
$720 \leq x \leq880$
So, the daily intake of the supplement should be between720mg and880mg.
