If a toy costs $20 and you have $50, how much money do you have left after buying the toy?

• A. $20
• B. $30
• C. $40
• D. $10

Answer: (B)

To determine how much money is left after purchasing the toy, you start with the total amount you have, which is $50. Next, subtract the cost of the toy, which is $20, from this total. The calculation looks like this: $50 (initial amount) - $20 (cost of the toy) = $30 (amount remaining). This results in having $30 left after the purchase. Understanding this concept involves recognizing that subtraction is used to find the remainder of funds after spending a portion of them. Therefore, the amount left after buying the toy is indeed $30.
