A company makes two calculator models, one designed specifically for financial use and the other designed for scientific use. The financial model contains 10 microcircuits, and the scientific model contains 20. A contract with a supplier of semiconductor chips requires the use of at least 3200 chips each day. A contract with a supplier of the off-on switches used in both calculators requires the use of at least 300 switches each day. The company would like to produce at least 100 financial models each day. If each financial calculator requires 10 production steps and each scientific calculator requires 12 production steps, how many calculators of each type should be produced to minimize the number of production steps
