Estimated crude oil reserves in a certain year was about 1,100 billion barrels. If the average consumption of crude oil is x barrels per day, what equation describes how many days the oil reserves will last?
A) $y = \frac { 1,100 \times 10 ^ { 9 } } { 365 x }$
B) $y = \frac { 1,100 } { x }$
C) $y = \frac { 1,100 } { 365 x }$
D) $y = 1,100 \times 10 ^ { 9 } x$
E) $y = \frac { 1,100 \times 10 ^ { 9 } } { x }$

The equation $y = \frac { 1,100 \times 10 ^ { 9 } } { x }$ correctly calculates the number of days the oil reserves will last by dividing the total reserves by the daily consumption rate.
