Answer :

Answer: £214

Step-by-step explanation:

She works 18 hours in total for week days.

So, 8 x 15 = £120

And, 3 x 10 = £30 for extra hours

120 + 30 = £150

On Saturday she works 4 hours.

8 x 2 = 16 per hour as it doubles

So, 16 x 4 = £64

Finally, £150 + £64 = £214

£214 for last week

 Sarah earned £ 214 in the last week.

How know how much Sarah have earned?

Total hours Sarah worked from Monday to Friday                                          =   ( 2.5 + 3 + 5.5 + 2 + 5) hours = 18 hours

  • As we know for Monday to Friday the pay out is £8 per hour for the first 15 hours and £10 per hour for any extra hours

∴ From Monday to Friday Sarah earned = £ {( 15 x 8) + ( 3 x 10)} = £ 150

Again according to the problem,

  • For Saturday, the normal rate gets doubled.
  • Sarah worked 4 hours in Saturday.

∴ She earned £ ( 4 x 16) = £ 64

Total earning of last week  = £ ( 150 + 64) = £ 214
