Answer:
$662.77
Step-by-step explanation:
Data provided in the question:
Amount Mary owes = $750
Discount rate, r = 16%
Time period = 10 months = years = 0.833 years
Now,
Amount Mary owes = Loan Amount × ( 1 + r )ⁿ
or
750 = Loan amount ×
or
750 = Loan Amount × 1.131
or
Loan Amount = $662.77
The amount of the loan she should ask for so that her proceeds are $750 is $662.77

Answer: a) 800
b)
Step-by-step explanation:
The exponential growth function is represented by :-
, where A is initial value , b is the multiplicative rate of change and t is the time period.
Given : A bacteria culture starts with 100 bacteria and doubles in size every half hour.
i.e. A = 100 and b=2
Then, the exponential growth function to find the number of bacteris after t hours :_
At x=3
Hence, the there are 800 bacteria after 3 hours.
