Sure,I do not agree because the answer is -20>-27
<span>In this case, every bottle has 500 mg of caffeine with a standard deviation of 25 mg. The equation of a bottle will be: 500 +/- 25mg caffeine per bottle.
To calculate a carton containing 30 bottles, you just need the equation with 30. It will become: (500x30) +/- (25x30)mg= 15000 +/- 750 mg of caffeine per carton</span>
I believe the correct answer is D. Thank you.
6(4x+5)=3(x+8)+3
24x+30 = 3x+24+3
24x-3x = 24+3-30
21x = -3
x = -3/21 = -0,14
