A craftswoman produces two products: floor lamps and table lamps.

Production of one floor lamp requires 75 minutes of her labor and materials

that cost Php25.00. Production of one table lamp requires 50 minutes of

labor, and the materials cost Php20.00. The craftswoman wishes to work no

more than 40 hours each week, and her financial resources allow her to pay

no more than Php900.00 for materials each week. If she can sell as many

lamps as she can make and if her profit is Php39.00 per floor lamp and

Php33.00 per table lamp. How many floor lamps should she make each week

to maximize her weekly profit? How many table lamps should she make each

week to maximize her weekly profit? What is that maximum profit?
