Diego's checking account after the transfer?
A. $419.90 B. $453.73 C. $458.28 D. $477.58

Answer 1

Let's calculate the amount in Diego's checking account step by step.

1. Starting balance on Friday: \[ \text{Starting balance} = 512.40 \]

2. Deposit on Saturday: \[ \text{New balance after deposit} = 512.40 + 150.25 = 662.65 \]

3. Withdrawal on Saturday: \[ \text{New balance after withdrawal} = 662.65 - 62.80 = 599.85 \]

4. Transfer 30% of the current balance to savings on Sunday:

   • Calculate 30% of the checking account balance: \[ \text{Transfer amount} = 0.30 \times 599.85 = 179.955 \]

   • Since we typically round to two decimal places for currency: \[ \text{Transfer amount} \approx 179.96 \]

5. Calculate the remaining balance after the transfer: \[ \text{Remaining balance} = 599.85 - 179.96 = 419.89 \]

Thus, the amount left in Diego's checking account after the transfer is approximately $419.89. However, looking at the provided options:

• A. $419.90
• B. $453.73
• C. $458.28
• D. $477.58

The closest correct answer based on slight adjustment in rounding would be A. $419.90.
