a) 40 miles of ribbon can be made

b) 64 miles of ribbon can be made

What is a function?

We know that the term function has to do with a mathematical model. We can use the function for the purpose of prediction just as we do in this problem that we have here.

a) In the first instance, a machine can make 5 miles of ribbon in an hour. We have said that the amount of the ribbon should be r and the hours should be x. We now have;

r =5x

After eight hours we have

r = 5(8)

r = 40 miles

b) If it makes 8 miles of ribbon in an hour;

r = 8x

r = 8(8)

r = 64 miles
