On a $500 loan, Carla paid $60 interest at a rate of 8%. How long did she have the loan?

1 year, 5 months or 17 months

Step-by-step explanation:

Interest (I) = $60

Principal (P) = $500

Rate (R) = 8%

Time (T) =?

Since, Simple Interest (I) = (P x T x R) / 100

making T the subject of formula;

T = 100I / P x R

Inputting the values

T = 100 x 60 / 500 x 8

T = 6000 / 4000

T = 1 year, 5 months

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
