Sarah's mom gave her $79 to go shopping. She bought a sweater for $30, a T-shirt for $7, and a pair of shoes for $26. How much money does Sarah have left?

1. Break Down the Problem

To find out how much money Sarah has left after her shopping, we will:

1. Calculate the total amount spent on her purchases.
2. Subtract the total amount spent from the initial amount of money Sarah had.

2. Relevant Concepts

The relevant operation here is subtraction:

• Total Money Sarah Had: $79
• Total Money Spent: (Cost of Sweater + Cost of T-shirt + Cost of Shoes)

3. Analysis and Detail

1. Calculate the total cost of the items:

   • Sweater: $30
   • T-shirt: $7
   • Shoes: $26
   • Total Cost = $30 +$7 + $26

   $\text{Total Cost} = 30 + 7 + 26 = 63 \text{ dollars}$

2. Calculate the amount of money Sarah has left:

   • Money Left = Total Money - Total Cost

   $\text{Money Left} = 79 - 63 = 16 \text{ dollars}$

4. Verify and Summarize

After calculating the total expenses and subtracting them from the initial amount, we found that Sarah has $16 left. The calculations have been verified and are correct.

Final Answer

Sarah has $16 left after her shopping.
