Sean deposited $200 into an account and earned $36 in interest after 3 years. use the formula l = prt, where l represents simple interest, p represents principal, r represents interest rate, and t represents time in years. what is the interest rate? is it a) 0.06 b) 0.6 c) 6.0 d) 60

The correct option is :  A) 0.06

Explanation

The formula of Simple Interest:   , here P = Principal amount, I = amount of interest earned, r = rate of interest in decimal and t= time in years.

Given that, Sean deposited $200 into an account and earned $36 in interest after 3 years. So here, P = 200 , I = 36 and t = 3  

Plugging those values into the above formula.....

So, the interest rate is 0.06

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
