Calculate simple interest earned on a deposit of $1000 at a rate of 3% for 10 years.

260%

Step-by-step explanation:

10 years = 120 month

1000-100%

x-3%

1) (3*1000)/100 = 30$

3600-x

3) (3600*100)/1000 = 360%

4) 360%-100%=260%

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:
