Aman invested $500 in the stock market. during the first week, he gained $200.during the second week, the market was strong and the man doubled his money. during the third week , stocks fell, and the man lost $650. how much money did the man have at the end of three weeks ?

He would have $750 at the end of three weeks

 500 + 200 = 700        700  x  2 + 1400

1400 - 650 = 750

$750 at the end of three weeks

unless if u could do my questions, if not i wouldn't want to

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
