Annika took a 4x6 inch photo to a print shop and had an enlarged print made that is 12x18 inches. In the original photo, Annika is holding up a book and the book cover is 0.75x1.2 inches. What is the area of the book cover on the enlarged version of the photo?

The area in the enlarged version is (2.25 * 3.6) square inches

Step-by-step explanation:

Here, we want to get the area of the book in the enlarged version

From what we have

initial version is;

4 * 6

enlarged is 12 * 18

It means that; the dimensions were tripled from the initial to the enlarged

So a book cover of initial:

0.75 by 1.2

Its enlarged form will be;

(0.75 * 3) by (1.2 * 3)

= 2.25 * 3.6

45

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
