Answer:
60
Step-by-step explanation:
180-140=40, 180-(80+40)=60
value of home in 1991= 105% of 170000
value of home in 1992= 105%×105% of 170000
value of home in 1993= 105%×105%×105% of 170000
=$196,796.25
Slope intercept form is

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

Subtract 6x to both sides:

Divide 5 to both sides:
Area=14.6
To find a trapezoid
Top +Bottom /2 multiplied by height
So 2.5+ 4.8= 7.3
7.3/2= 3.65
3.65x4=14.6
