The way you get this is you look at how angle D and A are the same for both triangles. given this, they are equal to each other. So you'd do 2y-5=65. You will get 35. 35=y, so substitute that in for your other equation. You will get 2x+35=90.6. solve that and you will get 27.8=x
First multiply 20 by .3 (30%) This will give you a product of 6. Subtract 6 from 20 (14) $14 added to $20 is equal to $34 Ramon spent $34 on the pullovers
