Final answer:
The future minimum wage needed to reach the poverty line for a family of three after accounting for 25% inflation over five years would be $13.39 per hour.
Step-by-step explanation:
To calculate the required future minimum wage to keep up with inflation and reach the poverty line, we need to adjust the current minimum wage for the expected inflation rate and consider the poverty threshold. With a current minimum wage of $7.50 falling short of the poverty line for a family of three, being only 70% of the necessary amount, we aim to find the adjusted amount for 100% of the poverty line after five years of inflation.
First, let's find the amount that represents 100% of the poverty line based on the current minimum wage:
- Current minimum wage that brings a family to 70% of the poverty line: $7.50
- To find the full 100%, we divide $7.50 by 70% (or 0.7): $7.50 / 0.7 = $10.71 (rounded to two decimal places)
Now, we have to adjust the $10.71 to account for the 25% inflation over the next five years:
- Adjusted wage = Current full poverty line wage * (1 + inflation rate)
- Adjusted wage = $10.71 * (1 + 0.25)
- Adjusted wage = $10.71 * 1.25
- Adjusted wage = $13.39 (rounded to two decimal places)
Therefore, in five years, with a 25% inflation rate, the minimum wage should be increased to $13.39 per hour to be at the poverty line for a family of three.
