Final answer:
Jose and Valeria should save 20% of their total monthly net earnings ($10,000), which equals $2,000, according to the 80/20 savings rule.
Step-by-step explanation:
The question involves applying the 80/20 savings rule, which suggests saving 20% of your income and spending the remaining 80%. To calculate how much Jose and Valeria should save every month, we'll first need to determine their total monthly net earnings:
- Jose's earnings: $4,000
- Valeria's earnings: $6,000
- Total earnings: $4,000 + $6,000 = $10,000
Next, we calculate 20% of their total earnings to find out the savings amount:
20% of $10,000 = 0.20 × $10,000 = $2,000
Therefore, according to the 80/20 savings rule, Jose and Valeria should save $2,000 every month.
