Answer:

  (i) $1528.80

  (ii) $2402.40

  (iii) $41.39/h; 13.7% increase

Step-by-step explanation:

(i)

The weekly wage is found by multiplying hours by the number of dollars for each hour:

  weekly wage = (42 h)($36.40/h) = $1528.80

__

(ii)

58 hours of work represents a straight week and 58 -42 = 16 hours of overtime. The overtime rate is 1.5×$36.40 = $54.60 per hour. Then the overtime pay is ...

  (16 h)($54.60/h) = $873.60

The technician's total wage for 58 hours of work is ...

  total wage = straight pay + overtime pay

  = $1528.80 +873.60

  total wage = $2402.40

__

(iii)

The hourly rate is found by dividing the pay by the corresponding number of hours.

  rate = $1490/(36 h) ≈ $41.39 /h . . . . . . . actually 41.38 8/9 per hour

The percentage increase is ...

  ((new amount) -(original amount))/(original amount) × 100%

  = (4.98888...)/36.40 × 100% ≈ 13.7% . . . increase

_____
