Question

Brandon owns 4 times as many soccer cards as Paul. Brandon owns 36 soccer cards. What is the
equation to determine the number of soccer cards that Paul owns?

Answer 1

B = number that Brandon owns

P = number that Paul owns

 

Given:

 

B = 4P

B = 36

 

Solve for P from the two equations above:

 

4P = 36

P = 36/4 = 9

 

Paul owns 9 cards.

Answer 2

Chris,

You can use the same strategy for all four problems that you posted.

1. Set up variables. Usually let x represent whatever follows "as" if there is a comparison. In this case you have "Brandon owns 4 times as many soccer cards as Paul.

                                                    Let x=# of cards Paul owns. Let 4x = # of cards Brandon owns

2. Write expressions/equations that show relationships in the problem.

    You are given that Brandon owns 36 cards, so 4x = 36.

3. Isolate your variable and solve.

              4x = 36         I think this equation is good for what is asked. You don't need to solve but I did below.

              4x/4 = 36/4

                x = 9

4. Use the same approach with your other problems.
