Final answer:
Rasheed donated $784 last October for underprivileged children.
Step-by-step explanation:
In this problem, we are given that Rasheed's bank account and withdrawals totaled -784 this October, which means he had a deficit of 784. We are also told that this October, he collected half as much as last year. Let's say the amount he collected last year is x. Therefore, this October, he collected x/2.
Now, we can set up an equation to find the amount Rasheed donated last October. We know that his total collections minus his withdrawals should equal the deficit in his bank account. So, we have:
x/2 - x = -784
Simplifying the equation, we get:
-x/2 = -784
Multiplying both sides of the equation by -2, we get:
x = 2 * -784
Solving for x, we find that the amount Rasheed collected last year was 1568. Therefore, the amount he donated last October would be half of that, which is 784.
