<span>Let’s
assign variables for each workers
Let x = number of boxes sorted by worker 1
Let y = number of boxes sorted by worker 2
Let Z = number of boxes sorted by worker 1
=> X = 3Y
=> X = 2Z
The equation would be:
=> X + Y + Z = 66
=> X + X/3 + X/2 = 66
=> 6X + 2 X + 3 X = 396
=> 11 X = 396
=> 11X / 11 = 396 / 11
=> X = 36
X = 36
Y = 36 / 3 = 12
Z = 36 / 2 = 18
=> 36 + 12 + 18 = 66

4.5x+7.05y=$43.65
x+y=8
Timed 4.5 for both side to get
4.5x+4.5y=36
4.5x+7.05y=43.65
-
4.5x+4.5y=36
=
2.55y=7.65
y=3 pounds
x=5 pounds. Hope it help!
If the last digit in 1.50 is less than 5, then remove the last digit.
If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is less than 9, then remove the last digit and add 1 to the second to the last digit.
If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.
