The linear equation that gives the cost C (in dollars) for j jerseys is [tex]C = 23j_{1} + 19.80j_{2}[/tex].
How do we derive a linear equation?
From the question, the linear equation that gives the cost C (in dollars) for j jerseys can be derived as follows:
[tex]C = 23j_{1} + 19.80j_{2} ............................. (1)[/tex]
Where:
C = total cost of the two jersey
Cost per unit of sports jerseys with $345 cost = $345 / 15 = $23
Cost per unit of jerseys with $495 cost = $495 / $19.80
[tex]j_{1}[/tex] = units of sports jerseys with $345 cost
[tex]j_{2}[/tex] = units of jerseys with $495 cost
