Faith earns $13.50 x 8 = $<<13.5*8=108>>108 per day.
Since she works 5 days a week, she earns 5 x $108 = $<<5*108=540>>540 per week.
She gets an additional 2 x $13.50 = $<<2*13.5=27>>27 per day for the overtime pay.
She earns a total of $27 x 5 = $<<27*5=135>>135 additional pay for her weekly overtime.
Therefore, Faith earns $540 + $135 = $<<540+135=675>>675 per week.
