Answer:
30.8
Step-by-step explanation:
First make the percentage into a decimal. You do this by moving the decimal to the left 2 digits
19.5% → 0.195
Then, multiply both numbers
0.195 × 158 = 30.81
But, we are not done yet. We need to round 30.81 to the nearest tenth.
The digit in the hundredths place is less than 5, so it rounds down.
30.81 → 30.8
Therefore, your answer is 30.8
