Sadie already had $36 saved up, and then her grandparents gave her $50 for her birthday. Sadie spent $10 on a new phone case. Which expression tells you the amount of money Sadie has left?

1 answer

To find the amount of money Sadie has left after her transactions, you can start with how much she had initially, add the money she received from her grandparents, and then subtract the amount she spent.

  1. Start with the amount she already had: $36
  2. Add the birthday money: $36 + $50
  3. Subtract the amount spent: ($36 + $50) - $10

So the expression that tells you the amount of money Sadie has left is:

\[ (36 + 50) - 10 \]

This simplifies to:

\[ 86 - 10 \]

Therefore, Sadie has $76 left after her transactions.
