Suppose that the world's current oil reserves is R = 2110 billion barrels. If, on average, the total reserves is decreasing by 18 billion barrels of oil each year, answer the following:
A.) Give a linear equation for the total remaining oil reserves, R, in terms of t, the number of years since now. (Be sure to
use the correct variable and Preview before you submit.)
R=
billions of barrels.
B.) 13 years from now, the total oil reserves will be
C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted (all used up)
approximately
years from now.
(Round your answer to two decimal places.)
