B= 53 because the angle measure 37 and B should add up to 90.
C=37 because angle b and c should add up to 90

It was divided by 2 so it can be the amount the bracelets cost. Or instead of dividing to get 250, You can multiply and do 2x125=250, So them add Go on from there, Its not to hard but if you need more help I'm here!

Now for the necklace portion of it. 3x80=240, So she sold 80 necklaces. Than sold 3 more. Now you have a total of 250.
