Chapter 4.1, Problem 53ES

a)

To determine

Solution of the given system of equations using graphingwhere, “We plan to start taking an aerobics class. Nonmembers pay $ $4$ per class. Members pay a $ $10$ monthly fee plus on additional $ $2$ per class. The monthly cost, $y$ of taking $x$ classes can be modeled by the linear system:
$y=4x$ $\to$ Nonmembers;
$y=2x+10$ $\to$ Members”

b)

To determine

Interpretation of the coordinates of the solution in practical of the given system of equations using graphing, “We plan to start taking an aerobics class. Nonmembers pay $ $4$ per class. Members pay a $ $10$ monthly fee plus on additional $ $2$ per class. The monthly cost, $y$ of taking $x$ classes can be modeled by the linear system: $y=4x$ $\to$ Nonmembers; $y=2x+10$ $\to$ Members”
