Question 1056805
<pre><b><font size=4>
Let the certain number be x

What he should have gotten = x-15

What he actually got = x+25, which is given = 145

So:

          x+25 = 145
             x = 120

Therefore:

What he should have gotten = x-15 = 120-15 = 105
   
{{{matrix(1,8,

((matrix(4,1,what,he,actually,got))-(matrix(5,1,what,he,should,have,gotten)))/((matrix(5,1,what,he,should,have,gotten))),

{{{matrix(1,12,
