Final answer:
Alma's parents would need to save $4,166.67 per month for the next 3 years to reach their goal of $150,000.
Step-by-step explanation:
To calculate how much Alma's parents would need to save each month for the next 3 years, we need to find the total amount they need to save and divide it by the number of months. Alma's parents want to save $150,000 over 3 years, which is a total of 36 months (3 years * 12 months). So, they would need to save $150,000 / 36 = $4,166.67 per month.
