A = oz of the solution A
b = oz of the solution B
The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.
a + b = 80
0.45a + 0.95b = 0.65*80
by solving the above system of equations you'll find····
a = 48 oz
b = 32 oz

Place the compass at one point and extend it halfway through the segment and draw an arc. Then use the same setting on the compass to draw another arc from point B. Then, use the ruler and the pencil to draw a line through the two points of intersection of the arcs. that is the perpendicular bisector. Hope this helps!
