Lucas esta buscando piso. ¿que oferta tiene el mejor precio por m cuadrado? VILLASUR ENSANCHE: superficie: 0,75 dam cuadrados su

Jet001 [13]

Answer:

Area 1 is the best option

Step-by-step explanation:

Given Data:

Area 1 = 0.75 dam square

Price = €11,620

Area 2 = 0.009 ha

at €193,500

Area 3 = 0.84a

at €68,900

Where ha ( hectare )

a ( area )

Solution

First we convert all areas to square meter ( m² )

Area 1 = 100 * 0.75 dam square

= 75m²

Cost of area 1/ square meter

= €11,620 / 75m²

= €154.93 / square meter

Area 2 = 0.009 ha * 10,000

= 90m²

Cost of area 2 / square meter

= €193,500 / 90m²

= €2,150 / square meter

Area 3 = 0.84a * 100

= 84m²

= Cost of area 3 / square meter

= €68,900 / 84m²

= €820.23 / square meter

slope as you should already know is rise/run, or how much something moves in relation something else, namely how much the y-axis go up as the x-axis moves sideways, one moves, the other follows, but the increments will be different, sometimes the same, but usually different.

the y-intercept means, when the graph of the equation touches or intercepts the y-axis, and when that happens x = 0, or the horizontal distance is at bay.

for the slope on 6), 30 or 30/1 means, for every 1 year(x) passed, the worth(y) increased by 30, or jumped by 30 units, so as the x-axis moved 1, the y-axis moved 30. After 12 years 30 * 12 = 360, and we add the initial 720 and we end up with 1080.

the y-intercept, well, as aforementioned is when x = 0, is year 0.
