Answer: Yes. There's a proportional relationship

Step-by-step 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.

The relationship between speed (s), distance (d), and time (t) is s = d/t. Substituting the given information, we see that 105/t < 70105 < 70t1.5 < t So, the time will be AT LEAST 1.5 hours. Hope this helps.
