Question

Please please help! DUE MIDNIGHT!!!!!

Samantha finds a bank, Star Bank, which offers a CD account with a 2% interest rate every month. Star Bank’s interest is not compounded. The interest is
based on the original amount of deposit. Remember that Samantha has $500 to start the account. She will not withdraw or deposit more money in the account for 2 years.

5. Fill in the table showing the amount of money in the Star Bank CD account over 4 months.

Months 0 1 2 3 4
Amount in CD account $500.00


6. Is the relation a linear function? If so, state the rate of change and write the equation of the relation, where x is the number of months and y is the amount in the account. If not, explain why not.

Answer 1

we have to convert 2% in to a decimal then multiply it into the x-value which is the months with the addition of 500 because that is the start value.If you were to graph this it would be a linear fuction, y=0.2x+500. The rate of change is found by slope, so rise over run. taking 2 points on the graph and do this
(y 2-y 1)/(x 2-x 1) and graph the equation and get two of the points and find the slope for the rate of change.
