u have this information

purchase ---> reward
50   ---> 3
100 ---> 6

this gives u a slope
$$ \large m=\frac{6-3}{100-50}=\frac{3}{50}=0,06 $$

I got a different answer than what helder got, I'm not too sure of it though.

the_fizicx99 · Answer

I don't know where he got 100 x and 6y. He multiplied it by 2, I don't know why he did that .-.

anonymous · Answer

$0 if x < $50
$3 if x >= 50

the_fizicx99 · Answer

I thought of using x ≥ 50

anonymous · Answer

this question makes no sense

helder_edwin · Answer

i think @sourwing 's answer is better. i didn't read the problem throughly.

helder_edwin · Answer

and yes. the last part doesn't make sense.

the_fizicx99 · Answer

Ohhh, I think I have an idea of what it suppose to look like!  It says y = 3 and y = 0.03x 

So 3 = 0.03x

Then plug in random values for x and see when they both equal 3, that's when they will have an intersection

the_fizicx99 · Answer

I'm onto something, not sure how to explain it though lol

helder_edwin · Answer

I guess that makes sense.

anonymous · Answer

Yeah, that's it. The paragraph in my original post was a different question in the same section so I thought they were similar kind of like a two part question

the_fizicx99 · Answer

You can also plot y = 3 and y = 0.03x and see when they intersect

...maybe?
