In 50 years stock A realises 15*50 + 130 = $880
in 50 yeras stock B gives 50(1.09)^50 = $2676.87
2676.87 - 880 = $ 1796.87 / share
Its C
M.N and O are 60 degree. And you have to know that 30 60 and 90 triangle. if 30 degrees opposite is measuring A , 60 is A square root 3 and the 90's opposite is being 2A. So 90 degree opposite is 16 square root 3 and 30 degree is being 8 square root 3 and 60 is

the height is 24 .
Let x is the small drink
x +0.5 is the large drink (cause large drink cost 50 cents more than small drink)
<span>3 small drinks and 2 large drinks</span> should be:
3x + 2(x +0.5)
= 3x + 2x + 1
= 5x +1
Expression: 5x +1
