Answer:
Each person would pay $37.87.
Step-by-step explanation:
1. You would do $87.95 times 7.75% (87.95 * 0.0775) which should be $6.81. You would add $6.81 to $87.85 which would equal $94.67
2. Multiply $94.67 by 20% (94.67 * 0.2) which should equal $18.93. Add that to $94.67 and you will get $113.60.
3. Divide $113.60 by 3 (113.60 / 3) which should be the final answer of $37.87.
Answer:
The population is expected to double in 36 years
Step-by-step explanation:
According to the the rule of 72,
A value is doubled if the product of the annual rate and number of years is 72,
Given,
The annual rate of interest = 2%
Let x be the time in years after 1965,
By the above statement,
The population will double if,
x × 2 = 72 ⇒ x = 36
Hence, the after 36 years since 1965 the population will be doubled,
i.e in 2001. ( ∵ 36 years after 1965 )
