Answer:
C = 9x +2280
Step-by-step explanation:
The 2-point form of the equation for a line can be a place to start.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
C = (4800 -3000)/(280 -80)(x -80) +3000 . . . . . use given values
C = 1800/200(x -80) +3000 . . . . simplify some
C = 9x -720 +3000 . . . . eliminate parentheses
C = 9x +2280
Count all the squares to get the answer (the long ones that are connected are 10)
Answer:
Step-by-step explanation:
The growth factor is 1.06.
The year is 2020 - 1978 = 42.
This is exponential growth as the growth factor is > 1.
The equation is V = 40000(1.06)^42
V works out to $462,281
