Answer:
£34.45
Step-by-step explanation:
Paul,colin and brian are waiters. One night the restaurant earns tips totalling £77.50.They share the tips in the ratio 1:3:5.
The sum of their Proportion is
1 + 3 + 5 = 9
For Brain
5/9 × £77.50 = £43.06
For Paul
1/9 × £77.50 = £8.61
Hence:
How much more does brian get over Paul?
This is calculated as:
£43.06 - £8.61
= £34.45

Answer:
9%
Step-by-step explanation:
You are going to want to use a modified compound interest formula, as shown below. This version of the compound interest formula is what you use to solve for the interest rate.
![r = n[(\frac{A}{P})^{1/nt}-1]](https://tex.z-dn.net/?f=r%20%3D%20n%5B%28%5Cfrac%7BA%7D%7BP%7D%29%5E%7B1%2Fnt%7D-1%5D)
<em>r = interest rate (decimal)</em>
<em>n = numbers of times compounded (annually)</em>
<em>A = total amount</em>
<em>P = principal amount</em>
<em>t = time (years)</em>
Now, lets plug in the values:
![r = 3[(\frac{1,780.74}{1,046})^{1/(3)6}-1]](https://tex.z-dn.net/?f=r%20%3D%203%5B%28%5Cfrac%7B1%2C780.74%7D%7B1%2C046%7D%29%5E%7B1%2F%283%296%7D-1%5D)
r = 9% interest rate
Step-by-step explanation:
the vertex is the point, where the parabola turns around. it is (depending on its orientation, if it is opening upwards or downwards) the maximum or the minimum of the curve.
so, as we can see on the grid, that point is x = -3, y = +1 = (-3, 1).
so, B is correct
