You can put this solution on YOUR website! Your sister's store is given $200 to start off, and makes a $40 profit every week afterwards. Write an inequality to find the minimum number of weeks it will take your sister to have a profit of 100
**
Use the standard form of equation for a straight line: y=mx+b, m=slope, b=y-intercept
For given problem:
slope,m=$40/week
y-intercept,b=-$100
x= minimum number of weeks it will take your sister to have a profit of 100
inequality:
40x-200>100
40x>300
x>7.5 weeks
