.75 x .7 + .3 y= .7
.525 + .3 y = .7
.175 = .3 y
y = .58333
58.3%. This doesn't mean you can stop trying though! Give 100 Percent ;).

0.7*75 + 0.3n = 70
0.3n = 70 - 52.5 = 17.5
n = 58.3%

Set it up:
(0.75 * 0.70) + ( X * 0.30) = 0.70
Solve for X.
X= 58 1/3 percent
Done.

Don't worry you will pass on your present course.
