Lucy bought a plant and planted it in a pot near a window in her house. The plant grew at a rate of 2.5 inches per month and its height at the time of purchase was 10 inches. Make a table of values and then write an equation for the function H(t),H(t), representing the height, in inches, of the plant tt months after Lucy bought the plant.

Work Shown:

x = unknown horizontal length

1/5 = 0.2

Perimeter = 2*(width + length)

P = 2*(0.2 + x)

P = 0.4 + 2x

Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x

0.4 + 2x = 1.5

2x = 1.5-0.4

2x = 1.1

x = (1.1)/2

x = 0.55

x = 55/100

x = (5*11)/(5*20)

x = 11/20
