Can someone answer this for me? it’s number 12 and number 12 only. i appreciate it.

Assuming that this only for you math class, you would use the simple interest formula, the one your teacher normally uses.

The formula is I= PRT

The letters in the formula basically mean principle (amount of money) rate, and time.

But, if you might have noticed, I and PR are already given. We just need to find time.

So, what you'd do instead is use the formula is I/P = T

.05/2000= .00025

In other words, 2 years and one month. (25 months)

So, your answer is just 2 years and one month.

18

Step-by-step explanation:

SI= p*r*t/100

P=2000

R=5%

T= x

2000*5*x/100=100x

2000+100x= 3800

100x= 3800-2000= 1800

X= 1800/100= 18

step-by-step explanation:
