My instinct is that $20 per A would not be enough to move the needle, and might be net-harmful when you consider intrinsic motivation. But how about $500 per A? (Or $1000 for straight As) Still might be cheaper than tutoring?
Sorry for the late reply, but $20 per A (times 7 subjects) was $140 which was more than my annual allowance at the time ($2/wk), and grades came out 4 times per year, so this was a significant amount of money for me, particularly before I was 14 and could legally get a job.

Interestingly, lots of people now seem excited about alpha school, where pay-for-performance is apparently a core principle!
