A joinery produces two types of school chairs: a basic model and an executive model. Basic chairs require 2 hours for assembly and finishing, while executive chairs require 3 hours. The tapestry requires 1 and 2 hours for the basic and executive chairs, respectively. For the assembly and finishing of the chairs there is a weekly availability of 280 hours per week and for the tapestry there is an availability of 150 hours per week. If the revenue for basic chairs is R $ 80 per unit and for executive model chairs is R $ 130.00 reais, how many units of each type should be produced each week to maximize the profit of the joinery?
