Let s = selling price
s+-+.1s+%3E=+11025
.9s+%3E=+11025
s+%3E=+12250 answer
-----------
Let g be the final grade
%282%2F3%29%2A48+%2B+%281%2F3%29g+%3E=+70
%282%2F3%29%2A48+%2B+%281%2F3%29g+%3C=+79
1st equation:
32+%2B+g%2F3+%3E=+70
g%2F3+%3E=+38
g+%3E=+114
2nd equation
32+%2B+%281%2F3%29g+%3C=+79
g%2F3+%3C=+47
g+%3C=+141
--------
114+%3C=+g+%3C=+141 answer
