He saves $200 (the amount of change over the original amount $500
200/500 = 2/5 and 2/5 = 40% (divide 2 by 5 and get .4 which = 40%)
40% discount is the answer to your question
Shape b has the shaded area closest to 63%
Answer:
3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°
Step-by-step explanation:
Triangle g
180° = 80° + 3y + 2y
100° = 5y
y = 20°
Triangle h
y = 180° - 130°
y = 50°
180° = 4x + x + 50°
130° = 5x
x = 130 / 5
x = 26°
