Answer:
Let the cost of orange be X and cost of cherry be y 
3x + 9y = 78
8x + 4y = 58 
Solving equation using elimination method
multiplying eq 1 with 8 and eq 2 with 3 
8(3x + 9y ) = 78(8)
3( 8x + 4y) = 3(58)
24x + 72 y = 624 
24x + 12y = 174 
subtracting, 
60 y = 450 
y = 7.5 
3x + 9(7.5) = 78
3x + 67.5 = 78
3x = 78 - 67.5
3x = 10.5 
x = 3.5 
<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>

Hi there! 
Let's prove segment AB is perpendicular to CD. Attention to the fact that a two column proof has to be concise. So all the comments can't be exhaustive, but as short as possible.
Let's recap: An isosceles triangle is one triangle with at least 2 congruent angles.
