For starters, create an equation to show David's earnings. We can do this using Danielle's as a basis, which is set up as y=(# of hours)x+(bonus). This gives us y=12x+80. Now, as we need both their ys to be equal, we just set both equations equal to each other, making 15x+50=12x+80. Now, we solve for x, starting with 15x+50=12x+80, subtracting 12x from both sides to get 3x+50=80, subtracting 50 from both sides to get 3x=30, and dividing three from both sides to get x=10. To check, we just plug in our answer to both equations and see if the ys match up. With Danielle's equation, we get y=15(10)+50=150+50=200 and with David's equation, we get y=12(10)+80=120+80=200, proving that our answer is correct.

Explanation:
Each pencil has a profit of Rs 1.25 since 
Multiply that result with 20 to get the final answer shown above in bold.
Answer:
1.8 cycles
Step-by-step explanation:
The average number of clock cycles per instruction is given by the sum of the product of each possible number of cycles by its likelihood.
1 cycle: 50%
2 cycles : 25%
3 cycles : 20%
4 cycles : 5%

The average number of clock cycles per instruction is 1.8.
Answer:
726
Step-by-step explanation:
If you take the number 200 and add 526 to it, it equals 726.
