Answer : The cost of 21 meter of ribbon is, $28.5

Step-by-step explanation :

As we are given that, the cost of 14 meter of ribbon is $19.

Now we have to determine the cost of 21 meter of ribbon.

As, the cost of 14 meter of ribbon = $19

and, the cost of 1 meter of ribbon = [tex]\frac{1}{14}\times \$ 19[/tex]

So, the cost of 21 meter of ribbon = [tex]\frac{21m}{14m}\times \$ 19[/tex]

                                                        = $ 28.5

Therefore, the cost of 21 meter of ribbon is, $28.5
