Answer:
<u>Diego paid $52 for 12 books. </u>
Step-by-step explanation:
If Mike bought 3 books for $13 that means that a book cost him $ 4.33
$ 13/3 = $ 4.33
And if Diego bought 12 books for the same price, how much did it cost?
An equation called "<em>Rule of 3 </em>" is used:
1 book = $ 4.33
12 books = X
The X of the equation is cleared:
X = (12 books * $ 4.33) / 1
<u>
X = $ 52 for the 12 books Diego bought. </u>
Well 13 /3 = 4.3333, that sure the cost for one book and the rate. so if he bought 12 books at the same rate, then its 12*4.33333. which equals 52 dollars
