Answer:
x=2
Step-by-step explanation:
add 2x to both sides and subtract 5 from both sides
6x = 12
divide by 6
x=2
One way to test this is by using the equation for Ken on Maureen. Let's say in the first hour,
f(t) = 200(0.976)^1 = 195.2 mg
In the second hour,
f(t) = 200(0.976)^2 = 190.52 mg
In the third hour,
f(t) = 200(0.976)^3 = 186 mg
If you compare this with Maureen's data which is 150, 90 and 54 for the first, second and third hour, respectively, you will see that Maureen's rate is much faster. However, you cannot tell by what factor because the function is exponential, not a multiple. There is no constant difference between their rates. Therefore, we only know that Maureen's rate is much faster.
The answer is <span>Maureen's body eliminated the antibiotic faster than Ken's body.</span>
5.88 / 3 = 1.96 per pound
original price - 1.21 per pound
Just choose x = 0,1,2,3 and find y for each x, for each of the tables.
