If the simple interest on $6,000 for 2 years is $840 , then what is the interest rate?

7 %

Step-by-step explanation:

i do not know if you use this but I use S. I=P*R/100*T S. I=840 P for principal (the money you borrow or lend) = 6000 T for time=2 years. R for rate=? In order to find out the rate, you need to substitute all these numbers into their respective places. 840=6000*r/100*2 6000/100=60 840=60*r*2 840=120r r=7%
