Chris wants to order dvds over the internet each dvd costs $15.99 and shipping the entire order costs $9.99 if he can spend no more then $100 how many dvds could he buy?

5 would cost $80 and shiping is $10 so he can only buy 5

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
