1,000, 2% , 9 months find the simple interest

I = 15

Step-by-step explanation:

The formula for finding interest is I=PRT.

I = Interest

P = Principal (dollars)

R = Rate (percent in decimal form)

T = time (in years)

So, I = 1000×0.02×0.75

Multiply those numbers, and get 15 as interest.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
