Question 572418
She needs to order 5-ounce and 8-ounce cups. The storage room will only hold 10 more boxes of cups. A box of 5-ounce cups costs $15 and a box of 8-ounce cups costs $18. A maximum of $90 is budgeted for cups. Give two possible combinations of cups Susana can order.
---------------------
Equation:
f + e <= 10 boxes
15f+18e <= 90 dollars
--------------------------------
Modify for graphing:
f <= -e + 10
f <= (-6/5)e + 6
--------
{{{graph(400,400,-10,30,-10,30,y < -x+10, -x+10, y < (-6/5)x+6), (-6/5)x+6)}}}
======================
One solution: 2 boxes of 5 ounce and 3 boxes of 8 ounce
2nd solution: 2 boxes of 5 counce and 2 boxes of 8 ounce
