Answer: Yes. There's a proportional relationship
Explanation:
We are told that Anthony and Miguel go to the store to purchase some new DVDs and that an advertisement in the window catches their attention as they saw that:
3 DVDs cost $22,50. This means the price of one will be:
= $22.50 / 3
= $7.50
5 DVDs cost $37.50. This means that the price for one will be:
= $37.50 / 5
= $7.50
Since the price of a DVD both cost $7.50, it means that the information on the sign represent a proportional relationship.
