Answer:
8 percent
Step-by-step explanation:
Since the formula for interest rate is the original money, the amount of years, and the inetrest rate multiplied together, we could plug it into an equation. 6000 times 4 times the ineterest rate is equal to 1920. 6000 times 4 is 24000. 1920 divided by 24000 is equal to 0.08 or 8 percent.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
