Since 32 mil is 1/10 of the US pop, multiply 32 mil by 10 so you get the 10/10 aka the whole US pop. That means it would be 320,000,000. All you do is add a zero to 32 mil since you multiply by 10. 32 mil originally had 6 zeros. After multiplying, you have 7 zeros.
Answer:
Yes this is a linear function f(x) = ex+30
e = hourly rate
x=hours
f(x) = total earnings
Cent is by the hundred so one percent is 1/100 so .6%=6/1000
which can be reduced to 3/500
The answer is root. Hope this helps!
