Sasha would have saved $350 after 15 months.
To write an equation that gives the total amount saved as a function of the number of months, you can use the following formula:
Total amount saved = $50 + $20 * number of months
This equation represents the total amount saved as the initial amount saved ($50) plus the amount saved each month ($20) multiplied by the number of months.
For example, if Sasha has saved for 15 months, the total amount saved can be calculated as follows:
Total amount saved = $50 + $20 * 15
Total amount saved = $50 + $300
Total amount saved = $350
Therefore, after 15 months, Sasha will have saved $350.
