Question

Snookers Lumber can convert logs into either lumber or plywood. In a given day, the mill turns out three times as many units of plywood s lumber. It makes a profit of $20 on a unit of lumber and $50 on a unit of plywood. How many of each unit must be produced and sold in order to make a profit of $17680

Answer 1

17680 = 20x + 50y
y = 3x
where y = plywood units
x = lumber units
so 17680 = 20x + 50(3x)
17680 = 20x + 150x
17680 = 170x
104 = x
Lumber units = 104
Plywood units = 312

Answer 2

correct

Answer 3

y=3x (y=plywood, x= lumber)

20x+50y=17680

20x+50(3x)=17680
20x+150x=17680
170x=17680
x=104
y= 3(104)
x=104, y=312

Answer 4
