SOLUTION: In 1975 the population of the Earth was approximately 4 billion and doubling every 35 years. The formula for the population P in year Y for this doubling rate is P(in billions)=4X2

Question 89349: In 1975 the population of the Earth was approximately 4 billion and doubling every 35 years. The formula for the population P in year Y for this doubling rate is P(in billions)=4X2^[(y-1975)/35]
What will the population of the US be in 2025 if this growth rate continues

The formula for the population P in year Y for this doubling rate is
P(in billions)=4X2^[(y-1975)/35]
What will the population of the US be in 2025 if this growth rate continues
-----------
P = 4*2^[(2025-1975)/35]
P = 4 * [2.6918000...]
P = 10.76720... billion
