Answer: £ 8

Step-by-step explanation:

Total hours Lena works from Monday to Friday = 34 hours

Hours she works on Saturdays = 4

Overtime rate of Saturday = 1.5 times her normal rate

Let x be the normal rate.

Then , Her total earning = $34 x + 4 \times(1.5x) =34x+6x=40x$

Since her total earnings for week = £ 320

So,

$320=40x\\\\\Rightarrow\ x=\dfrac{320}{40}\\\\\Rightarrow\ x=8$

Thus, her normal rate of pay per hour = £ 8
