The answer is C

Explanation: each ride costs $1.25 but they don’t give a number of rides therefore the number of rides is unknown and represents X. 64 was the total value of his money before the rides. With each ride you add -1.25 to 64, which gives diminishing returns for each ride.

if the population of a country increases at a rate of 1.5% annually, and it’s current population is 430,000, how many years will

aleksandrvk [35]

Hi,
$a_0=430000\\
a_1=a_0*1.15\\
a_2=a_1*1.15=a_0*1.15^2\\
...\\
a_n=a_0*1.15^n\\

a_n \geq 3*a_0\\

1.15^n \geq 3\\

n*ln(1.15) \geq ln(3)\\

n \geq \dfrac{ln(3)}{ln(1.15)} \\

n \geq 7.86059688...\\\\

\boxed{n \geq 8}\\
