s2008m [1.1K]

Answer:

Step-by-step explanation:

Mr Thomas earns 18.80 per hour for the first 40 hours of work in a week. This means that the total amount that he earned in the first

40 hours of work would be

40 × 18.8 = $752

He earns 1 and a half times and that amount per hour for each hour he works over 40 hours in a week. This amount per hour would be

1.5 × 18.8 = $28.2

Last week, Mr Thomas worked 45.5 hours. The extra hours that he worked is 45.5 - 40 = 5.5 hours.

Amount earned for 5.5 hours is

5.5 × 28.2 = $155.1

Total amount that Mr Thomas earned is

752 + 155.1 = $907.1
