I will provide two solutions.
First solution is of the 5-th grade level student, who just solves problems on division and multiplication
of integer numbers, but does not know proportions yet.
Second solution is of the level of the 6-th grade level student, who just learned proportions.
You select the one of these two solutions, which suits better your needs and your level.
First solution of the 5-th grade level student
12 photos cost &36 dollars - hence, one photo costs 36/12 = 3 dollars.
Then 5 more than 12 photos costs (12+5)*3 = 17*3 = 51 dollars.
It is your ANSWER : 51 dollars.
Second solution of the 6-th grade level student
Make a proportion
= ,
where 'x' is what you want to get.
Simplify the proportion
= .
Now from the proportion find x = = 3*17 = 51 dollars.
It is the same value, as in my first solution above.
Solved in two different ways for your better understanding.
--------------------
By the way, the meaning of the proportion is that the unit price for one photo is the same in both cases.
