<h3><u>Answer:</u></h3>

The function N(t) is given as:

N(t)=3+(0.25t)^3-8(1.06)^t

<h3><u>Step-by-step explanation:</u></h3>

Jenny studied the characteristics of two species of bacteria.

The number of bacteria of species A, A(t), after t hours is represented by the function:

A(t) = 5+(0.25t)^3

The number of bacteria of species B, B(t), after t hours is represented by the function:

B(t) = 2 + 8(1.06)^t

N(t) denotes the difference in the number of bacteria; hence N(t) is given by after t hours as:

N(t)=A(t)-B(t)

N(t)= 5+(0.25t)^3-(2 + 8(1.06)^t)

which on simplifying gives:

N(t)=5+(0.25t)^3-2-8(1.06)^t\\\\N(t)=5-2+(0.25t)^3-8(1.06)^t\\\\N(t)=3+(0.25t)^3-8(1.06)^t

Hence,

Answer:

The original price of the item is $28.

Step-by-step explanation:

So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.

So:

First convert 25% to a decimal, 0.25.

OP(original price) = 21 ÷ 1 - 0.25 =

1 - 0.25 = 0.75

21 ÷ 0.75 = 28.
