Question

The table below shows the value of two different antiques over a period of five years.

Value of Two Antiques Over Five Years
Year 1 2 3 4 5
Antique 1 $100 $108 $116 $124 $132
Antique 2 $70 $77 $84 $89 $97
Which of the antiques has a value that has been increasing at a constant rate? What is that rate? Explain your reasoning.

Answer 1

As we can see the first antique is increasing by 8$, while the second one is increasing by 7$. The answer would logically be the first antique since it has a higher rate and has higher amount paid to get for. So the answer is the first Antique.
