Answer 2

Answer:

Girl daily spend 50 cent .      

Step-by-step explanation:

Formula

$Average = \frac{Sum\ of\ all\ observation}{Number\ of\ observation}$

As given

In 36 days a girl spent 18 dollars.

$Average = \frac{Total\ amount}{Number\ of\ days}$

Putting all the values in the formula

$Average = \frac{18}{36}$

Average = $0.5

i.e

Girl spend daily $0.5 .

As 1 dollar = 100 cent

Convert $0.5 into dollars .

$\ 0.5 = 0.5\times 100$

$\ 0.5 = \frac{5\times 100}{10}$        

                  = 50 cents

Therefore girl daily spend 50 cent .
