Question

snookers lumbers can convert logs into either lumber or plywood in a given day the mill turns out twice as many units of plywood as lumber it makes a profit of $20 on a unit of lumber and $40 on a unit of plywood how many of each unit must be produced and sold in order to make a profit of $10100

Answer 1

Let the number of units of lumber = x
Then number of units of plywood = 2x

Profit earned on x units of lumber = 20 * x = 20x
Profit earned on 2x units of plywood = 40 * 2x = 80x

ATQ, 20x + 80x = 10100
100x = 10100
x = 10100/100 = 101

Therefore, number of units of lumber is 101 and
Number of units of plywood is 202


CHECKING :
101 x 20 = 2020
202 x 40 = 8080
------
10100

Answer 2

thanks harkirat can you help with this
solve by elimination method
5x+2y=-13
7x-3y=19

Answer 3

Hi Nancy can you help with this one
solve by elimination method
5x+2y=-13
7x-3y=19

Answer 4

Multiply first equation by 7 and second by 5 to get

35x + 14y = -91 ------- (A)
35x - 15y = 95 ------- (B)

Answer 5

Now subtract (B) frm (A) to get

29y = - 186
so y = - 186/29

Putting y = -186/29 in the given first equation 5x + 2y = -13, we get
5x + 2 (-186/29) = -13
5x - 372/29 = -13
5x = -13 + 372/29
5x = (-377 + 372)/29
5x = -5/29
x = -5/ (29 * 5)
x = -1/29
