Mamont248 [21]

Answer:

24 t shirts

Step-by-step explanation:

revenue - expenses = profit

profit = $71

expenses = $25

revenue = money made from t shirts = $4 for each t shirt, x times (she makes $4 for each t shirt and sells x t shirts) = $4 * x

4 * x - 25 = 71

add 25 to both sides to isolate the variable and its coefficient

4x = 96

divide both sides by 6 to isolate x

x = 24

How to graph -x + 2y = 6
larisa86 [58]
In order to graph the equation, you need some coordinates, 
So, put x = 0, 
2y = 6. y = 3.  Coordinate = (0, 3)

Now, put y = 0, 
-x = 6
x = -6   Coordinate (-6, 0)

In short, Just mark that two points and draw a line, graph is done

Hope this helps!
