MrMuchimi
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.

Guitar 1:       (($160 - $100) / $160) x 100% = 37.5%
Guitar 2:       (($250 - $150) / $250) x 100% = 40%

Thus, guitar 2 has a greater percent change in price.

Given: Line AD is congruent Line CD; Angle 3 is congruent to Angle 4
loris [4]

Step-by-step explanation:

Given : AD=CD and

           ∠3=∠4

To prove : Line DB bisects ∠ABC

                i.e.∠ABD=∠CBD

Proof :  Consider ΔABD and ΔCBD,

\angle3=\angle4\ \{given\}\\\\\implies 180\textdegree-\angle3=180\textdegree-\angle4\\\\\implies\angle 1=\angle 2

and

AD=CD\ \{given\}

and

BD=BD\ \{common\}

So, ΔABD ≅ ΔCBD (By SAS criterion}

Hence , By CPCT (corresponding part of congruent triangle}

∠ABD=∠CBD

Therefore, Line DB bisects ∠ABC.
