Answer:
[tex]\$47\ per\ week[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In his problem
The amount of savings per week is equal to the constant of proportionality k or slope of the linear equation
so
Looking at the graph
take the point (2,94)
x=2 weeks, y=$94
Find the value of k
[tex]k=\frac{y}{x}[/tex]
substitute the values of x and y
[tex]k=\frac{94}{2}[/tex]
[tex]k=\$47\ per\ week[/tex]
