Question 1162469
<br>
I think that by "differential pay scale", you mean his pay is
$2.15 each for the first 50
$3.15 each for the next 110 (up to 160)
$4.90 each for the next 40 (up to 200)
$6.25 each for the last 10<br>
Then his pay is<br>
{{{50(2.15)+110(3.15)+40(4.90)+10(6.25)}}}<br>
You can do the calculation as easily as we can....<br>
