Henry is taking a medicine for a common cold. The table below shows the amount of medicine f(t), in mg, that was present in Henr
Elden [556K]
Geometric sequence general form: a * r^n
For Greg, we are given the elimination of the medicine as a geometric nth term equation:
200 * (0.88)^t
The amount of medicine starts at 200 mg and every hour, decreases by 12%;
To compare the decrease in medicine in the body between the two, it is useful to get them in a common form;
So, using the data provided for Henry, we will also attempt to find a geometric nth term equation that will work if we can:
As a geometric sequence, the first term would be a and the second term would be ar where r = multiplier;
If we divide the second term by the first term, we will therefore get r, which is 0.94 for Henry;
We can check that the data for Henry can be represented as a geometric sequence by using the multiplier (r) to see if we can generate the third value of the data;
We do this like so:
282 * (0.94)^2 = 249.18 (correct to 2 d.p)
We can tell that the data for Henry is also a geometric sequence.
So now, we just look at the multiplier for Henry and we find that every hour, the medicine decreases by 6%, half of the rate of decrease for Greg.

The answer is therefore that <span>Henry's body eliminated the antibiotic at half of the rate at which Greg's body eliminated the antibiotic.</span>

A restaurant customer left ​$1.30 as a tip. The tax was 7% and the tip was 10​% of the after tax cost. Which information is not
ziro4ka [17]

Answer:

Step-by-step explanation:

Given that:

Tip left = $1.30

Tax = 7%

Tip = 10% of after tax cost

The tax percentage is not needed in calculating the bill after tax and tip

Hence,

Let after tax cost = x

10% of x = 1.30

0.1x = 1.30

x = $13

After tax cost = $13

Hence, the Total bill after tax = $13
