11 people x 138 = 1,518 total pounds.
13 people x 148 = 1,924 total pounds.
Difference = 1924 - 1518 = 406 pounds.
Average weight = 406/2 = 203 pounds
Answer:
4.38%
Step-by-step explanation:
<em>Assuming simple interest</em>, we start by writing the formula for simple interest.

Where
SI is the interest amount (328.13)
P is the principal amount (2500)
r is the rate of interest (what we need to find)
t is the time, in years (t = 3)
Since we want rate of interest, we re-arrange the formula to get r in terms of the other variables. Shown below:

Now we simply plug-in the information we know and find r:

To convert into percentage, we multiply by 100:
r = 0.0438 * 100 = 4.38%
Answer:
option A is correct if operation A is correct make me as brainleylist
A. 7/4
Rate of change is the same as slope, it is how the line has to go to get from the first to the second point. The slope function is y2-y1 / x2-x1. So we end up with 8-1/5-1 making 7/4
