DUDE yo what is up he is paid 45.12
3/5 equals to 0.6 so it's less than 4.9
8 25/1000 = 8.025 <===
The whole number stays to the left of the decimal...and since the 25 is over 1000, the last digit has to be in the thousandths place.
The answer can be found by replacing x with 1 in 1 - x. Therefore f(1) equals 0
Hope that helps you
