Answer:
I think it would be 350$
Step-by-step explanation:
ok so you have to buy 10 shirts so you need to set up your problem which would be 10(12+8+15)
Then you would have to actually distribute which would give you 120+80+150
Finally you just add all of your numbers together which would be 350$
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> the number of solved puzzles
y -----> the number of solved riddles
we know that

The solution of the inequality is the shaded area above the solid line 
The slope of the solid line is negative 
The y-intercept of the solid line is the point (0,4)
The x-intercept of the solid line is the point (2,0)
therefore
The graph in the attached figure
It is 10 units². The difference between x and x is 5 and the difference between y and y is 2. 5 times 2 is 10. Hope this helps!
The general equation of a line is:

When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
