Compounded Interest Rate Formula: $\displaystyle A = P(1 + \frac{r}{n})^{nt}$

P is principle amount
r is rate
n is compounded rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 6000

r = 5% = 0.05

n = 1

t = 2.5

Step 2: Find Interest

Substitute in variables [Compounded Interest Rate Formula]: $\displaystyle A = 6000(1 + \frac{0.05}{1})^{1 \cdot 2.5}$
Simplify: $\displaystyle A = 6000(1.05)^{2.5}$
Evaluate: $\displaystyle A = 6778.36$

An amusement park sells child and adult ticket at a ratio of 8:1 . O. Sat. They sold.147 more child tickets than adults. How man

Sauron [17]

Ratio of child ticket and adult ticket is 8:1.
So we can let number of children tickets sold in Saturday = 8x

Number of adult tickets sold in Saturday = 1x = x

As given difference between child ticket and adult ticket in saturday = 147.

So 8x - x = 147

7x = 147

On dividing both sides by 7.

x = 21

So number of children tickets sold in Saturday = 8*21 = 168

Number of Adults ticket sold in Saturday = 1*21 = 21

So total number of ticket sold in Saturday = 168 + 21 = 189.
