We are given the equation:

\[
8 = \frac{100}{2^{(3 - 0.1t)} + 2}
\]

To solve for \( t \), we can follow these steps:

### Step 1: Isolate the exponential expression
Multiply both sides of the equation by the denominator \( 2^{(3 - 0.1t)} + 2 \):

\[
8 \left( 2^{(3 - 0.1t)} + 2 \right) = 100
\]

### Step 2: Expand the left-hand side
\[
8 \cdot 2^{(3 - 0.1t)} + 8 \cdot 2 = 100
\]

This simplifies to:

\[
8 \cdot 2^{(3 - 0.1t)} + 16 = 100
\]

### Step 3: Subtract 16 from both sides
\[
8 \cdot 2^{(3 - 0.1t)} = 84
\]

### Step 4: Divide both sides by 8
\[
2^{(3 - 0.1t)} = \frac{84}{8} = 10.5
\]

### Step 5: Take the natural logarithm (ln) of both sides
To solve for the exponent, apply the natural logarithm:

\[
\ln\left( 2^{(3 - 0.1t)} \right) = \ln(10.5)
\]

By logarithmic properties:

\[
(3 - 0.1t) \ln(2) = \ln(10.5)
\]

### Step 6: Solve for \( t \)
First, divide both sides by \( \ln(2) \):

\[
3 - 0.1t = \frac{\ln(10.5)}{\ln(2)}
\]

Now, solve for \( t \):

\[
0.1t = 3 - \frac{\ln(10.5)}{\ln(2)}
\]

Finally:

\[
t = \frac{3 - \frac{\ln(10.5)}{\ln(2)}}{0.1}
\]

Let me calculate the exact value of \( t \).The value of \( t \) is approximately \( -3.92 \).
