Answer:

$5.99

Step-by-step explanation:

We know that,

$4.46 = Rs. 324.06 (approx Rs. 325)

So,

Cost of 20 books= 325/15 ×20

= 65/3 ×20

= 1300/3

= Rs. 433.33 (approx Rs. 435)

= $5.99

Answer:

The cost of 20 book is $ 5.8 .

Step-by-step explanation:

Given information,

the cost of 15 books is $ 4.46

We have to find out the cost of 20 books

As,

The cost of 15 books = $ 4.46

The cost of 1 book =  \frac{the  \: cost \:  of  \: 15\:  book}{15}

The cost of 1 toy

 =  \frac{4.46}{15}

By dividing 4.46 by 15 we get

The cost of 1 book  = 0.29

The cost of 20 book = The cost of 1 book × 20

The cost of 20 book= 0.29 \times 20

The cost of 20 book= 5.8

Hence,

The cost of 20 book is $ 5.8 .
