Question

Guillermo has $320.16 in his account before making any transactions. Over the course of a week, he makes the following transactions: (See table below.) At the end of the week, how much money is in Guillermo's account?

a) $389.87
b) $710.03
c) $770.52
d) $427.31

Answer 1

After subtracting the sum of all transactions from Guillermo's starting balance, it appears that he has spent more than he had available, resulting in a negative balance. Consequently, none of the proposed answers seem to correspond with the calculation, suggesting an error in the question or missing information.

Step-by-step explanation:

To calculate the amount of money Guillermo has left in his account after making a series of transactions, we begin with his starting balance and then subtract the totals of each transaction listed. To solve this, we need to perform a series of subtraction operations:

• Starting balance: $320.16
• Subtract the sum of all transactions: $56.75 + $43.25 + $65.00 + $25.50 + $18.75 + $59.00 + $21.50 + $44.50 + $12.50 + $43.00 + $89.50 + $99.35 + $235.75 + $300.50 + $678.25

Adding all the transactions together gives us a total of $1,793.30. Now we subtract this amount from the starting balance:

$320.16 - $1,793.30 = -$1,473.14

Since we have a negative result, this indicates that Guillermo has spent more money than he had in his account, likely resulting in an overdraft situation. Therefore, none of the answer choices provided (a) $389.87, (b) $710.03, (c) $770.52, or (d) $427.31 match our calculation.
