Answer:
Written in Python
name = input("Name: ")
wageHours = int(input("Hours: "))
regPay = float(input("Wages: "))
if wageHours >= 60:
->total = (wageHours - 60) * 2 * regPay + 20 * 1.5 * regPay + regPay * 40
else:
->total = wageHours * regPay
print(name)
print(wageHours)
print(regPay)
print(total)
Explanation:
The program is self-explanatory.
However, 
On line 4, the program checks if wageHours is greater than 60.
If yes, the corresponding wage is calculated.
On line 6, if workHours is not up to 60, the total wages is calculated by multiplying workHours by regPay, since there's no provision for how to calculate total wages for hours less than 60

Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 =  1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
