The amount of money 'y' made at a laundromat after 'x' months can be represented by the linear function: y = 8.50x - 5. After 2 months, the laundromat made 20 dollars, but the linear function predicted they would make 12 dollars. What is the residual value for this data?

And the residual is defined as:

And replacing we got:

Step-by-step explanation:

For this case we know that the amount of money 'y' made at a laundromat after 'x' months can be represented by the linear function:

And fter two months we know that the laundromat made 20 dollars. And if we use the linear function we got:

And the residual is defined as:

And replacing we got:

207/8 is the right
