Question

Arnold deposited some money in a bank. The bank paid him a simple interest every year. After t years, the amount of money f(t), in dollars, that the bank paid Arnold was $1000 more than 20 times the number of years. Which statement best describes the steps to sketch a graph showing the relationship between f(t) and t?

Answer 1

Label t on the x axis and f(t) on the y axis and plot a graph having slope = 20 and y intercept = 1000.

Label t on the x axis and f(t) on the y axis and plot a graph having slope = 1000 and y intercept = 20.

Label f(t) on the x axis and t on the y axis and plot a graph

Answer 2

@JuanitaM ? Can you help? :)

Answer 3

Simple interest is I = PRT

Answer 4

ok, so they want you to see the F(t) = 1000 + 20t
do you understand that?

Answer 5

Yes, that part I get. :)

Answer 6

so what is the slope? y-intercept?

Answer 7

Slope would be 20 then? :)

Answer 8

Absolutely! so in order to answers these problems, right the function they give you and find the slope and/or y-intercept...

Answer 9

Y wold be f(t) right and t would technically be x?
