Sample Algorithm - Solutions

Dear Students,

I am providing some sample algorithms below for three exercises from the back of Chapter 1 in the textbook. My intention in providing these algorithms is to assist you in completing the Week 3 assignments.

Q. 17 on Page# 25

Step 1: Display a prompt for user to enter Radius
Step 2: Accept the Radius input from the user

Step 3: Display a prompt for user to enter Price
Step 4: Accept the Price input from the user

Step 5: Calculate and store the area of the Pie using this formula

                Area = Pi * radius * radius

                Where Pi = 3.142

Step 6: Calculate and store the Price per square inches

Step 7: Display a prompt for Price per square inches

Step 8: Display the value for Price per square inches

Q. 20 on Page# 25

Step 1: Display a prompt for user to enter the “Square yards of Mowing”

Step 2: Accept the input for “Square yards of Mowing” from user

Step 3: Display a prompt for user to enter the “Number of fertilizing applications”

Step 4: Accept the input for “Number of fertilizing applications”

Step 5: Display a prompt for user to enter the “Number of Trees to plant”

Step 6: Accept the input for “Number of Trees to plant”

Step 7: Calculate and store the cost of Mowing using “$30 per square yards” as the standard rate

Step 8: Calculate and store the cost of Fertilizing using “$30 per application” as the standard rate

Step 9: Calculate and store the cost of Planting trees using “$50 per tree” as the standard rate

Step 10: Calculate and store the overall total

Step 11: Display a prompt for the Overall Total

Step 12: Display the value of Overall Total to the user

Q. 24 on Page# 26

Step 1: Store “Total cost per semester”

Step 2: Store “Total units per semester”

Step 3: Calculate and store the per unit cost by dividing “Total cost” by “Total units”

Step 4: Calculate and store cost for math class by multiplying per unit cost by 4

Step 5: Calculate and store per week cost of math class by dividing the outcome from step 4 by 15

Step 6: Calculate and store per session cost of math class by dividing the outcome from step 5 by 3

Let me know if I can do anything else to assist you.

Thanks,

Ashish
