We have: I = P × R × T / 100
Here, I = 980
P = 7000
T = 8

Substitute their values into the expression:
980 = 7000 × R × 8 / 100
R = 980 × 100 / 7000 × 8
R = 98000 / 56000
R = 1.75%

In short, Your Answer would be 1.75%

Hope this helps!

What is simple interest?

Simple interest is the interest calculated on the principal portion of a loan or the original contribution to a saving amount.

Formula for simple interest

S.I = (P × R × T)/100

Where,

S.I is the simple interest

P is the initial principal balance

R is the interest rate

T is the time in years

According to the given question

We have

Simple Interest, SI = $980

Initial principal balance, P = $7000

Time, T = 8 years

Therefore, the annual interest rate for cd is given by

[tex]980=\frac{(7000)(R)(8)}{100}[/tex]

⇒ [tex]R =\frac{(980)(100)}{(7000)(8)}[/tex]

⇒ [tex]R=1.75[/tex]

Hence, the annual interest rate of cd was 1.75.
