A digital signal-processing application has 40000 lines. Basic COCOMO for embedded software uses multiplicative factor 2.8 and exponent 1.20. Find effort in person-months.
COCOMO effort is $E=a(KLOC)^b$. Here KLOC=40, so E=2.8×40¹·²≈234.23 person-months, closest to 234.25, A. Using raw LOC rather than thousands would produce the wrong scale.
