121.3 grams of caffeine is remaining in her blood
The given parameters are:
The amount of caffeine is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 175 * (1 - 11.5%)^t
At 3 hours, we have:
A(3) = 175 * (1 - 11.5%)^3
Evaluate
A(3) = 121.3
Hence, 121.3 grams of caffeine is remaining in her blood

-7 = -3x + b
i'm guessing because you have not provided a visual so i can not determine the B.
-4
-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10
^ ^
the ^ on the left is -5 and one number over is 4 which is the ^ on the right
do you have the picture I actually understand it if I see it in pictures .
