A company needs to develop digital signal processing software for one of its
newest inventions. The software is expected to have 40000 lines of code. The
company needs to determine the effort in person-months needed to develop this
software using the basic COCOMO model. The multiplicative factor for this model
is given as 2.8 for the software development on embedded systems, while the
exponentiation factor is given as 1.20. What is the estimated effort in person-months?
