$(5$ pts$.)$ A computer spends $30$ percent of the time on floating point operations, $20$ percent doing $\frac{\text{I}}{O},$ and $50$

percent on integer operations. Two improvements are being considered; enhancement $1)$ make integer operations

run two times faster, or enhancement $2)$ make floating$-$point operations run ten times faster. Use Amdahl's Law

to determine which enhancement is better
