btw this is math not chemistry 

Answer:

D) $690

Explanation:

Given:

Total hours worked by Derek = 43 hours

Rate of pay = $15 per hour

Rate of pay beyond 43 hours = $30 per hour

To determine:

The gross pay

Explanation:

Rate of pay for the first 40 hours = \(40\ hours * 15 /hour= 600\ dollars\)

Since the pay rate doubles after 40 hours,

Rate of pay for the remaining 3 hours = \(3\ hours * 30 /hour= 90\ dollars\)

\(Gross\ pay = Rate\ of\ pay\ for\ 40\ hrs + Rate\ of\ pay\ for\ 3\ hrs\)

Gross pay = 600 + 90 = 690 dollars
