The Barber family just left the local pet store with Lucky, their new family dog. The pet store owner told the Barber family that for the next six months, Lucky will grow at an average rate of four pounds per month. Currently, Lucky is three months old and weighs five pounds.

Age, in months 3 4 5 6 7 8 9

Weight, in pounds 5

Part A: Complete the given table that represents Lucky's current weight, in pounds, as a function of his age, in months.

Part B: Graph the data in the table from Part A. Be sure to label the graph and all data points.

Part C: Create a linear model that represents the Lucky’s current weight, in pounds, as a function of his age, in months.

Part D: If Lucky continues to grow at the rate of 4 pounds per month beyond the expected six months, how much will Lucky weight by time he is one year old?

P =[ (rM)/[1 – (1+ r/n)]^(-nt)] /  n

where P = the payment, r = the annual rate, M = the mortgage amount, t = the number of years, and n = the number of payments per year.

1558.09 = [ (0.05875M)/[1 – (1+ 0.05875/12)]^(-12(20)] /  12

The solve for M

M = 219684.92

Downpayment = 267900 -219684.92

Downpayment = 48215.08

Percentage of downpayment = (48215.08/267900) *100

= 18%
