Dodi wants to build a room for her piano. She makes a list of the materials needed: - At least 90 square feet of plywood for the surfaces
- At least 42 feet of wood planks for a platform for her plano
- Between 3 and 4 quarts of paint
Dodi's budget is $450. Plywood costs $3.75 per square foot, planks of wood cost $0.25 per
foot, and paint costs $24.00 per quart.
Let b represent Dodi's budget in dollars, p the area of plywood in square feet, w the
length of wood planks in feet, and the quarts of paint
Write inequalities to represent the material constraints and cost constraints in this
situation.
