Question

Michael was learning how to scuba dive. During his first lesson he dove 10 feet below the water’s surface, then he went up 15 feet and then back down 35 feet. Write the integer that represents Michael’s depth now?

A.-60

B.-30

C.60

D.40
What am I supposed to do here to get the answer?
he started out at zero, right? So now just add up all his movements:
0 - 10 + 15 - 35 = ___

Not sure how he could come up 15 feet after diving only 10 feet down, but maybe he jumped out of the water like a dolphin.
