Elegance Bath Products, Inc. (EBP) makes a variety of ceramic sinks and tubs. EBP has just developed a line of sinks and tubs made from a mixture of glass and ceramic. The sinks sell for P150 each and have variable costs of P80. The tubs sell for P600 and have variable cost of P450. The glass and ceramic sinks and tubs require the use of specialized molding equipment. The specialized molding equipment has 4,050 hours of capacity per year. A sink uses an average of 2 hours of specialized molding equipment time; a tub uses an average of 5 hours of specialized molding equipment time.

Assume that EBP can sell as many as 1,000 sinks and 500 tubs per year. How many tubs should EBP produce?
