To find the value of the stock after two years of increases, we can apply the percentage increases step by step.
1. **First year increase**: The stock increases by 31%. This can be represented as:
\[
\text{Value after first year} = x + 0.31x = 1.31x
\]
2. **Second year increase**: The value at the end of the first year is then increased by 16%. So we take the value after the first year and increase it by 16%:
\[
\text{Value after second year} = 1.31x + 0.16(1.31x) = 1.31x \times 1.16
\]
3. **Simplifying**: Now we calculate \(1.31 \times 1.16\):
\[
1.31 \times 1.16 = 1.5216
\]
Thus, the value of the stock after two years is:
\[
\text{Value after two years} = 1.5216x
\]
So, the expression that represents the value of the stock after two years is:
\[
1.5216x
\]
