For this case we have the following system of equations:
 y = -0.25x + 4.7

y = 4.9x-1.64
 When solving the problem graphically we must take into account the following:
 1) The solution of the system of equations is given by the intersection of both functions.
 2) The solution is an ordered pair of the form (x, y)
 For this case we observe that the solution is given by:
 (x, y) = (1.23, 4.39)

 Note: see attached image.
 Answer:
 
The approximate solution to the system is (1.23, 4.39)

The Chens bought their house for $240 000 twenty years ago. They just sold the house
serg [7]

The percent is the new value of the house of the price they paid 20 years ago is 216.67%.

<h3>Percentage</h3>

  • Old price = $240 000
  • New price = $520 000

percent is the new value of the house = New price / Old price

= 520,000 / 240,000 × 100

= 2.16666666666666

= 216.666666666666%

Approximately,

percent is the new value of the house = 216.67%

Therefore, the percent is the new value of the house of the price they paid 20 years ago is 216.67%.
