Answer 1

Answer:

SI = PNR/100

532 = 2800×n×7/100

532 = 28×7n

7n = 532/28

7n = 19

n = 19/7

n=2.71

Number of years = 2.71 or 19/7

Answer 2

Answer:

2.17 yrs

Step-by-step explanation:

P is the principal amount, $2800.00.

r is the interest rate, 7% per year, or in decimal form, 7/100=0.07.

t is the time involved, x...year(s) time periods.

So, t is x....year time periods.

To find the simple interest, we multiply 2800 × 0.07 × x= 532 to get

x= 2.17
