A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what integer represents her location relative to the surface after 7 seconds?

2.5 × 7 = 17.5

15.5 + 17.5 = 33


The scuba diver is -33 feet below the surface of water after 7 seconds.

Hope that helped! c:
