Given:
Fabric required for each chair = 10 yards
Fabric required for each sofa = 20 yards.
Total available fabric = 300 yards.
The number of sofas must be at least twice the number of chairs.
Profit on each chair = $50
Profit on each sofa = $80.
To find:
The function that represents the manufacturer's profit, P.
Solution:
Let P represents the manufacturer's profit, x represent the number of chairs and y represent the number of sofas.
Profit on 1 chair = $50
Profit on x chairs = $50x
Profit on 1 sofa = $80
Profit on y sofas = $80y
Total profit = Profit on x chairs + Profit on y sofas
Therefore, the required profit function is
.
