A store charges 6% VAT on all sales.<br>What is the total cost of a shirt marked at $30

AURORKA [14]

Answer:

$31.8

Step-by-step explanation:

Assuming the 6% tax is separate from the $30, we can use this equation:

Total = Cost + Tax (pretty self explanatory)

Method 1

Total = $30 + (6% * $30)

Total = $30 + $1.8

Total = $31.8

Method 2

Total = $30 * 1.06 (The 1 is the original cost, the .06 is the 6% tax)

Total = $31.8

Alisiya [41]

Answer:

$f(x)=5120(1.25)^{x}$

Step-by-step explanation:

As per the given question

As we know that

f(x) and x are related by following equation

$f(x)=a( {b})^{x}$

where

b is the common ratio

Now first we have to compute the value for b which are as follows

$\frac{6400}{5120}= 1.25$

$\frac{8000}{6400}= 1.25$

Like if we take the ratio by this method than it comes 1.25

Therefore the common ratio, b = 1.25

So,

a = 5,120

Hence, the equation which model the relationship between the number of weeks and the number of viewers is

$f(x)=5120(1.25)^{x}$
