Question 1148318: April is going to the bakery to purchase donuts and cinnamon rolls for the office personnel. She must purchase at least 30 items.

The system of inequalities you are asking for is


        d +     r <= 30     (1)      (counting items)

    0.75d + 1.25r <= 30     (2)      (counting total cost in dollars)
