Example Question #321 : Isee Lower Level (Grades 5 6) Mathematics Achievement

Sally bought 3 different picture frames and paid a total of $60. If the first frame cost $15 and the second frame cost $25, how much did the third frame cost?

Possible Answers:

Correct answer:

Explanation:

In order to find out how much the third frame costs, we need to subtract the cost of the first two frames ($15 and $25) from the total amount ($60).

There are two ways to subtract the cost of the first two frames from the total amount:

Method 1

We can subtract the total amount spent on the first two frames from $60

                                                      

Remember to follow Order of Operations (PEMDAS) and add the numbers in parenthesis first.

The cost of the third frame was $20

Method 2

We can subtract the cost of each frame from $60

The cost of the third frame was $20
