Question 1126405
<br>
When the calculations are described in words, different interpretations are possible.<br>
The other tutor used standard order of operations to convert the words into<br>
{{{10+x/2 = 25}}}<br>
With that interpretation, her answer of 30 is correct.<br>
But because the calculations are described in words, another valid interpretation is<br>
{{{(10+x)/2 = 25}}}
{{{10+x = 50}}}
{{{x = 40}}}<br>
So an answer of 40 is also valid for this problem.
