Hey there!!
Let us take the price of the redwood as ' x ' and pine as ' y '
Then , we take it into an equation. We get,
50x + 80y = 285 -------------- ( 1 )
80x + 50y = 339 -------------- ( 2 )
Now, multiply the first equation with 8 and the second equation with 5
400x + 640y = 2280
400x + 250y = 1695
Now subtract the second equation from the first
390y = 585
y = 585 / 390
y = $1.5
Now substitute this into any equation
50x + ( 80 ) ( 1.5 ) = 285
50x + 120 = 285
50x = 165
x = 165 / 50
x = $3.3
Redwood = $3.3
Pine = $1.5
Hope helps!
Cubes have 6 equal faces, and the surface area is the sum of all of these faces. Thus, one face would be 1/6 of the cube's surface area, or about 17%.
