Question

Find the range of allowable values based on the given information. round to the nearest tenth. 50; can vary by 30%

Answer 1

The allowable values are;

$35\text{ to 65}$

Here, we want to get the allowable values for the given information

To do this, we need to find the percentage value

That would be;

$\frac{30}{100}\times50\text{ = 15}$

Now, the allowable values can be in both direction

Greater than 50 or less than 50

When greater, we add; when lesser, we subtract

Thus, we have it as;

$\begin{gathered} 50-15\text{ to 50+15} \\ 35\text{ to 65} \end{gathered}$
