need help with "you have $15 in your bank account. you spend $11 on a hat. then you mow 3 lawns for $20 each and deposit the money into your bank account, write and solve an expression (using order of operations) to determine how much money is in your account." I keep getting $64.00 but my friend says that is not right.

(15 - 11) + (3 * 20) = 64

You are right.

To determine how much money is in your account after these transactions, let's break it down step by step:

1. Start with $15 in your bank account.
2. You spend $11 on a hat, which leaves you with $15 - $11 = $4 in your account.
3. Then, you mow 3 lawns for $20 each, which means you earn a total of 3 * $20 = $60.
4. Next, you deposit the $60 you earned into your bank account, which gives you $4 + $60 = $64.

Therefore, the correct answer is $64. It seems that you were correct in your calculation, and your friend may have made a mistake.

To determine how much money is in your account, we need to break down the problem step by step:

1. Initial amount: You have $15 in your bank account.
2. First expense: You spend $11 on a hat, so you subtract $11 from your initial amount: $15 - $11 = $4.
3. Mowing lawns: You mow 3 lawns, each paying $20. To find out how much you earn from mowing lawns, you multiply the amount earned per lawn ($20) by the number of lawns (3): $20 x 3 = $60.
4. Depositing money: You deposit the money you earned from mowing lawns into your bank account. To determine your account balance after the deposit, you add the amount earned ($60) to your previous balance ($4): $60 + $4 = $64.

So, according to the given problem, there should be $64 in your bank account. Your answer is correct. If your friend disagrees, they might have made a mistake in their calculation or misunderstood the problem. I hope this explanation helps!
