Answer 1

If for every 50$ spent, you get a 10$ credit, what would be the step function formula?

we have that

Let

x ----> amount spent

y ----> amount of credit

so

x/y=50/10

x/y=5

y=(1/5)x

For

$0\text{ < x }\leq50$

y=$10

For

$50\text{ < x }\leq100$

y=$20

For

$100\text{ < x }\leq150$

y=$30
