Speedup $(6$ points $-$ Correctness$)$: Show your work to receive full credit.

You have an optimization that speeds up floating point operations by a factor of $3,$ but does not help other instructions. You have another optimization that only speeds up non$-$FP instructions by $25\%($that is$,$ it speeds up those instructions by a factor of $1\mathrm{.}25),$ and you want to decide which to use. Suppose your favorite program has $15\%$ of its dynamic instructions FP operations. Further, assume FP operations have a CPI of $7\mathrm{.}0,$ while non$-$FP instructions have a CPI of $2\mathrm{.}5.$ If you can only select one of the optimizations, which should you use? Please provide the speedup for each optimization in isolation.
