B. $8

Step-by-step explanation:

Given:

Total payment, T = $160

Hourly rates = $t/hour

= total payment/total time worked

The question said, "worked 12 more hours than the amount she is paid per hour".

Total time worked = (12 + t) hour

Therefore, Hourly rates of payment, t = 160 / (12 + t)

t^2 + 12t - 160 = 0

Solving the above quadratic equation,

t = - 20 and 8

t = $8
