Using an exponential function, it is found that the colony will have 1344 bacteria after 8 days.
<h3>What is an exponential function?</h3>An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
Considering the initial amount of 150, and the growth rate of 73% each 2 days, the equation is given by:
Hence, after 8 days, the amount of bacteria is given by:

Answer:
The Amount of tax paid on the cell phone is $11.9
Step-by-step explanation:
Given as :
The cost of the cell phone = x = $170
The tax rate of the cell phone = r = 7% of the phone cost
Let The Amount of tax paid on the cell phone = $y
<u>Now, According to question</u>
The Amount of tax paid on the cell phone = 7 % of cost of the cell phone
i.e y = 7% of x
Or, y = × x
Or, y = × $170
Or, y =
∴ y = 7 × 1.7
i.e y = $11.9
So,The Amount of tax paid on the cell phone = y = $11.9
Hence, The Amount of tax paid on the cell phone is $11.9 Answer
