Answer:
7.25x + 22
Step-by-step explanation:
I believe that this equation relates to the slope-intercept form, so we know that for every game the group bowls the cost will increase by 7.25. We also know that 22$ is a set rate, therefore it will not change as they continue to bowl. So we add the x to 7.25 because it represents the slope in this situation, and 22 is set.
