Answer:
Please find the attachment for the required graph.
Step-by-step explanation:
We have been given that Madison deposited $18 in a savings account that earns 2.5% simple interest.
The graph of the given situation would be a linear function.
We know that simple interest formula is in form [tex]A=P+Prt[/tex], where,
A = Final amount,
P = Principal amount,
r = Interest rate in decimal form,
t = Time in years.
Let us convert given interest rate in decimal form.
[tex]r=\frac{2.5}{100}=0.025[/tex]
Substitute the given values in above formula:
[tex]A=18+18*0.025*t[/tex]
[tex]A=18+0.45t[/tex]
The equation representing the given scenario would be [tex]y=18+0.45x[/tex].
