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.

Answer 1

Sure! Let's choose three amounts from fictional concession stand prices. For this example, I will choose:

1. $2.75
2. $1.50
3. $3.25

Now, focusing on the hundredths place for addition, I will show the work step by step:

Step 1: Align the Numbers

   2.75
 + 1.50
 + 3.25

Step 2: Add the Amounts

Let's add them together, starting from the rightmost decimal place:

• Hundredths place: 5 + 0 + 5 = 10 (Write down 0, carry over 1)

• Tenths place: 7 + 5 + 2 + 1 (carry) = 15 (Write down 5, carry over 1)

• Whole numbers: 2 + 1 + 3 + 1 (carry) = 7

Putting it all together, we have:

   2.75
 + 1.50
 + 3.25
 ------
   7.00

Conclusion

The total amount spent was $7.00.

In this scenario, I bought popcorn for $2.75, a soda for $1.50, and candy for $3.25, making the total $7.00.
