You would mutliply however many points that 89% represents by 70%. Then you can play around with different test scores (multiplied by 30%) to determine what grade you'll get relevant to different scores.
You add the first value (multiplied by 70%) to the value that you get for the test score multiplied by 30%.

Your course work has earned you 89% of 70%, or 62% of the entire course. You only need another 8% to hit your desired score.
Now, consider the final; you get 30% if you score a perfect 100 on the exam. So, the ratio is you get 1% of the course for every 3.333 marks of your final. To hit 8% you need 8 * 3.333 which is approximately28 marks.
In conclusion, you need to score at least 28 out of 100 on your final to hit your overall 70% course target.

89 times .7 is 62.3
You have 62.3 points now and need 7.2 to receive a 70.
Thus, you need at least a 24 on the exam (24 times .3 is 7.2) which is 69.5

Jaredvs and Inspector both gave correct estimates.
Depending if your goal is an even 70 or 69.5 rounded up:
89(.70) + Exam(.30) = [69.5 or 70](100%)
62.3 + Exam(.3) = 69.5 or 70
Exam(.3) = 7.2 or 7.7
Exam = [7.2 or 7.7] / .3
Exam = [72 or 77] / 3
Exam = 24 or 25.66
Check:
89(.70) + [24 or 25.66](.30) ? >= 70 ?
62.3 + [7.2 or 7.7] = 69.5 or 70
So Jaredvs' estimate is the minimum score required.
