Practice with Sequence
2. Write an algorithm that converts a linear measurement in feet and inches into meters. One inch is equivalent to 2.54 centimeters.
Algorithm:
1. Prompt user for LengthInFeet.
2. Get LengthInFeet.
3. Prompt user for LengthInInches.
4. Get LengthInInches.
5. LengthInMeters = ((LengthInFeet * 12) + LengthInInches) * 2.54 / 100.
6. Display LengthInMeters.
IPO Chart:
Input
LengthInFeet
LengthInInches
Processing
Get LengthInFeet and LengthInInches
Calculate ((LengthInFeet * 12) + LengthInInches) * 2.54 / 100
Save the result in LengthInMeters
Display LengthInMeters
Output
LengthInMeters

Practice with Selection
4. Write an algorithm that can be used to calculate the commission earned in a real estate transaction. The chart below describes the formulas used to calculate the commission.
|
Sales Price
|
Commission
|
|
Less than $100,000
|
5% of Sales Price
|
|
$100,000 to $300,000
|
$5,000 + 10% of Sales Price over $100,000
|
|
More than $300,000
|
$25,000 + 15% of Sales Price over $300,000
|
Algorithm:
1. Prompt user for SalesPrice.
2. Get SalesPrice.
3. If SalesPrice< 100000
Commission = 0.05 * SalesPrice
Else If SalesPrice<= 300000
Commission = 5000 + (0.1 * (SalesPrice - 100000))
Else
Commission = 25000 + (0.15 * (SalesPrice - 300000))
4. Display Commission.
IPO Chart:
Input
SalesPrice
Processing
Get SalesPrice
If SalesPrice< 100000
Commission = 0.05 * SalesPrice
Else If SalesPrice<= 300000
Commission = 5000 + (0.1 * (SalesPrice - 100000))
Else
Commission = 25000 + (0.15 * (SalesPrice - 300000))
Output
