Krysta has $100 in a savings account that earns 5% annually. The interest is not compounded. How much interest will she earn in 2 years?

$225

Step-by-step explanation:

100 x 0.5

= 50 interest rate

100 + 50 = 150

Year two :

150 x 0.5

= 75

She will have $225 in her account in two years.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
