The Deep Dive
To find out when Alejandro and Alexia will have the same amount of money, we can set up equations based on their current amounts and monthly earnings or expenses. - Alejandro's amount after \( m \) months: \[ 116.20 + 39.10m \] - Alexia's amount after \( m \) months (subtracting the subscription cost): \[ 348.60 - 19m \] Setting these two equations equal to each other gives us: \[ 116.20 + 39.10m = 348.60 - 19m \] Now, let's solve for \( m \): 1. Combine like terms: \[ 39.10m + 19m = 348.60 - 116.20 \] \[ 58.10m = 232.40 \] 2. Divide both sides by 58.10: \[ m = \frac{232.40}{58.10} \] \[ m \approx 4 \] So, they will have the same amount of money in approximately 4 months.
