Answer:
A
Step-by-step explanation:
Sub in the point given, (3, 1), and check if the equation holds true
7(3) - 8(1) = 13
21 - 8 = 13
13 = 13
The equation held true, therefore, the point (3, 1) is a solution
For 12 number of aerobics classes, cost for members and nonmembers is same
<em><u>Solution:</u></em>
Let "x" be the number of aerobic classes
At a local fitness center, members pay a $12 membership fee and $3 for each aerobics class
Therefore,
Members pay = 12 + 3(number of classes)
Members pay = 12 + 3x ------- eqn 1
Nonmembers pay $4 for each aerobics class
Nonmembers pay = 4x ------- eqn 2
For cost for members and nonmembers be the same, eqn 1 must be equal to eqn 2,
12 + 3x = 4x
4x - 3x = 12
x = 12
Thus for 12 number of aerobics classes, the cost for members and nonmembers will be same
