Answer

After 9 months, both Trashia and Dak will have the same amount of money.

Solution

Let m represent the number of months. Trashia’s amount after m months: 83.40 + 28.70m Dak’s amount after m months: 458.70 − 13m Set the equations equal to find m: 83.40 + 28.70m = 458.70 − 13m Combine like terms: 28.70m + 13m = 458.70 − 83.40 41.70m = 375.30 Now, divide by 41.70: m = 375.30 / 41.70 m = 9 After 9 months, both will have the same amount of money.

Let's determine how many months it will take for Trashia and Dak to have the same amount of money. First, we can express the amount of money Trashia and Dak have after \( m \) months. - Trashia's money after \( m \) months: \[ 83.40 + 28.70m \] - Dak's money after \( m \) months: \[ 458.70 - 13m \] Now, we set these two expressions equal to find when they will have the same amount of money: \[ 83.40 + 28.70m = 458.70 - 13m \] Now, let's solve for \( m \): 1. Combine like terms: \[ 28.70m + 13m = 458.70 - 83.40 \] \[ 41.70m = 375.30 \] 2. Divide both sides by \( 41.70 \): \[ m = \frac{375.30}{41.70} \approx 9 \] So, after approximately **9 months**, both Trashia and Dak will have the same amount of money.
