x Scientists in a two-man submarine descend at a rate of 4 feet per minute for 7 minutes, then ascend 3 feet in the eighth minute to examine an object. The expression (-4) (7) + 3 represents the net change in the level of the submarine over the 8 minutes. What value represents the net change in the level of the submarine over the 8 minutes?
A: -31
B: 31
C: -25
D: 25
I apologize for the error in my explanation. You are correct. The correct calculation is:
(-4)(7) + 3 = -28 + 3 = -25
Therefore, the net change in the level of the submarine over the 8 minutes is -25.
So, the correct answer is:
C: -25

I have one riddle:
"I turn polar bears white and I will make you cry. I make guys have to pee, and girls comb their hair. I make celebrities look stupid and normal people look like celebrities. I turn pancakes brown and make your champagne bubble. If you squeeze me, I'll pop but if you'll look at me, you'll pop. What am I?
