Answer:
$171
Explanation:
We are asked to calculate his wage increase for a 36 hour work week.
Firstly, we calculate the amount he was earning at the old paying template where he was paid 14.05 per hour. Hence for a 36 weeks work hour, he would have earned 36 * 14.05 = $505.8
His new earnings per hour is 14.05 + 2.75 = $16.8
His earnings, based on new paying template would be 16.8 * 36 = $676.8
His increase in wages for a 36 hour work week would be $676.8 - $505.8 = $171
