Example 5: You work at an ice cream shop and need to order 5oz and 8oz cups. The storage room will only hold 10 more boxes. A box of 5oz cups costs $100 and a box of 8 oz cups costs $150. A maximum of $1250 is budgeted for yogurt cups. Write a system of linear inequalities that shows the number of boxes of each that could be bought. Graph your result. y
x
note: perhaps a better way to graph this would be to find the intercepts (set x= 0 and solve for y, then y=0 and solve for x)
