Answer:
Because we knew that the function rule for the input/output table is to multiply by 6, just multiply 7 by 6 and we get y = 42
For the second question, we also knew that the function rule for the input/output table is to divide by 3, just divide 6 by 3 and we get y = 2
Since we already knew that the charge for downloading a movie is $3, then we can also predict that x is number of movies downloaded, and the total fee for downloading x movies should be 3x, plus the monthly fee, we have the equation: y = 3x + 6.50
