Question 165629: Your computer supply store sells two types of inkjet printers. The first, type A, costs $137 and you make a $50 profit on each one. The second, type B, costs $100 and you make a $40 profit on each
one. You can order no more than 100 printers this month, and you need to make at least $4400 profit on them. If you must order at least one of each type of printer, how many of each type of printer should you order if you want to minimize your cost?

A+%2B+B+%3C=+100
50A+%2B+40B+%3E=+4400
Lets solve the first equation for either A or B;
B = 100-A
Now plug this into the second equation for b;
50A+%2B+40%28100-A%29+%3E=+4400
50A+%2B+4000-40A+%3E=+4400
10A+%2B+4000+%3E=+4400
10A+%3E=+400
A+%3E=+40
Now we have A, lets plug that into the first equation;
40+%2B+B+%3C=100
B%3C=+60
check;
50%2840%29%2B+40%2860%29%3E=+4400
2000%2B2400%3E=4400
