Kara had a savings account balance of $153 on Monday on Tuesday she has six withdrawals of $15.72 and a deposit of $235.15 what
trasher [3.6K]

Answer:

$293.83

Step-by-step explanation:

She started with $153. The next day she withdrew $15.72 six times, that is $15.72*6 = $94.32

We have to subtract $94.32 from the starting amount, that is $153 - $94.32 = $58.68

After that, she deposited $235.15. We have to add that to the current balance.

Now she has $58.68 + $235.15 = $293.83

Therefore, her account balance after these transactions is $293.83
