Lincoln invests money in an account paying simple interest. He invests $50 and no money is added or removed from the investment. After one year, he has $51.50. What is the simple percent interest per year?

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
