, or .9, however you would like to put it.
Answer:
the amount is 16,000,000
Step-by-step explanation:
first let that amount be Y for an example. so...





so the amount you are looking for is 16,000,000
y = 5x, so 5 is the constant of proportionality
We have by distributivity of limits over sums, and continuity of
and
, that

Given
, it follows that
