Suppose that the world's current oil reserves is R = 2200 billion barrels. If, on average, the total reserves
are decreasing by 15 billion barrels of oil each year, answer the following:
A.) Give a linear equation for the total remaining oil reserves, R, in billions of barrels, in terms off, the
number of years since now. (Be sure to use the correct variable.)
R=-15t+2200
B.) 15 years from now, the total oil reserves will be 1975
✓billions of barrels
C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted all
used up) approximately 146.60
x years from now.
(Round your answer to two decimal places.)
