Build a sugar-cube pyramid as follows: First make a 5 × 5 × 1 bottom layer. Then center a 4 × 4 × 1 layer on the first layer, center a 3 × 3 × 1 layer on the second layer, and center a 2 × 2 × 1 layer on the third layer. The fifth layer is a single 1 × 1 × 1 cube. Express the volume of this pyramid as a percentage of the volume of a 5 × 5 × 5 cube.

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
