US President Collin Hawkins is concerned about the economy. He orders the Treasury to issue direct stimulus payments to citizens in an effort to prevent a recession. On average citizens save 25% of their income. The total of this stimulus amount is $2 trillion USD. What is the multiplier for this stimulus injection? What is the total economic impact of this injection? *instead of using ' 0 's, simply note the number using "m", "b", or "t" for 'million,' 'billion,' or 'trillion.' For example if your answer is " $56,100,000,000 ", you should instead type "$56.1b".
