Bryan's hockey team is buying jerseys. It costs $250 for a one time set up fee and $23 for each jersey. Write an equation C(x), the cost of x jerseys.
Find C(5), the cost of 5 jerseys.
C(x)=250+23x
C(5)=250+23(5)
C(6)=365

State the Correlation Coefficient
Explain what the Correlation Coefficient suggests in the context of this problem.
y=-4.9x+101.05
r=-0.98
This is a strong negative correlation. This means that as the number of hours spent on social media increases, the score on the math tests decreases.
