Question

1. kori (k) has 13 playstation games. brian (b) has 4 more than kori.

how could you model this situation to help you find out how many games brian has? choose all that apply.
a. $k+13=4+b$
b. $b=k+4$
c. $k=b-4$
d. $9=k+b$

Explanation:

Step1: Analyze given relationship

We know Brian's games ($b$) are 4 more than Kori's ($k$).

Step2: Write direct equation

This translates to $b = k + 4$.

Step3: Rearrange the equation

If we solve $b = k + 4$ for $k$, we get $k = b - 4$.

Step4: Eliminate invalid options

Option A does not match the relationship, and Option D uses an unrelated total (9) which is not given.

Answer:

B. $b = k + 4$
C. $k = b - 4$
