If I did

(.30)+(.35*2)+(.05*4)+(.15)+(.15*10)

Would I be using the formula properly

4. (15 points) Assume the following instruction mix for a given benchmark program: 30% stores, 35% loads, 5% branches, and 15% integer addition, and 15% integer multiply. (a) Given a program with 200 instructions and that load instructions require two cycles, branches require 4 cycles, integer addition and store instructions require one cycle and integer multiplies require 10 cycles, compute the overall cycles-per- instruction or CPI. (b) Determine the Millions of Instructions per Second (MIPS) rate for a 800-MHz processor. (c) What is the execution time for this program? Be sure to include units when applicable
