Part One: Add and Subtract Decimals

Question

For this portfolio, you will need your concession stand portfolio list. You will use ONLY
the data from your hundredths place value for prices on your equations for this
portfolio.
1.) Choose any 3 amounts (you must have at least 2 amounts with decimals
that were not zeros). Then add them together. You MUST show your work.
After you have completed your equation you will need to write at least 1
complete sentence telling what what bought and how much the total was.
2.) Choose any 3 amounts (you must have at least 2 amounts with decimals
that were not zeros and at least 2 should be different from above). Then
subtract them. You MUST show your work. After you have completed your
equation you will need to write at least 2-3 sentences explaining what steps
you took or strategy you used to solve the equation.

Answer 1

Sure! Here’s a breakdown of how to complete the tasks you provided using decimal amounts. I'll create hypothetical prices for your concession stand portfolio and demonstrate the calculations needed for each part.

Part One: Add and Subtract Decimals

Concession Stand Prices:

• Popcorn: $3.45
• Soda: $2.55
• Candy: $1.25
• Chips: $1.50
• Hot Dog: $4.10

1.) Adding Decimals

Prices Selected:

• Popcorn: $3.45
• Soda: $2.55
• Candy: $1.25

Calculation:

   $3.45
+  $2.55
+  $1.25
---------
   $7.25

Total Amount: The total amount spent on popcorn, soda, and candy was $7.25.

2.) Subtracting Decimals

Prices Selected:

• Hot Dog: $4.10
• Chips: $1.50
• Soda: $2.55

Calculation:

   $4.10
-  $1.50
---------
   $2.60

Then, we'll subtract the soda from that total:
   $2.60
-  $2.55
---------
   $0.05

Explanation: To solve the subtraction problem, I first subtracted the price of the chips ($1.50) from the hot dog ($4.10), which resulted in $2.60. I then subtracted the price of the soda ($2.55) from that result. This gave me a final total of just $0.05. The steps involved careful alignment of the decimal places to ensure accuracy in the calculations.
