Answer: 2008
Step-by-step explanation:
Given : The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the equation
, where x is the number of years after 2000.
To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get
The required year will be = 2000+8=2008.
Hence, in 2008 the federal debt will be $10.68 trillion.
The common factors for 28 and 42 are 1, 2, 7 and 14.
Add 10 to 894.
894 + 10 = 904
