Your friends ate at a restaurant and left a $2.40 tip. They left a 15% tip. What was the cost of their bill before the tip?
zhannawk [14.2K]

Answer:

16$ is the bill

Step-by-step explanation:

so 2.40 is 15% of the bill, what i'd do is first divide 2.40(15%) by 3 to get 5% which can make this much easier, 2.40÷3=0.80. this means that 1.60 is 10% since 0.80 is 5%. so now we do 1.60×10=16$

Maureen is taking an antibiotic. The table below shows the amount of antibiotic f(t), in mg, that was present in her body after
MariettaO [177]
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>
