Answer: $34.6
Explanation:
The question is 20% tip of $173.26 dinner bill.
First we round to the nearest ten dollars means round off to the nearest tenth
Since 0.26 is not up to 0.5, we round down and the value becomes $173
Next, 20% of $173 means 20/100 × 173
=0.2 × $173 = $34.6
Therefore, 20% tip on a $173 dinner bill is $34.6
