Answer:
Warning Signs Your Tires Need to Be Rotated
Uneven wear between tires. Tire one side wear. ...
Vehicle vibration. At speeds of 45 mph and higher, you may feel a vibration, which may be caused by uneven wear. ...
Pressure loss. If one tire loses air slowly, yet faster than the others, it may mean too much pressure is put on it.
There are three unknowns in this problem. First, let's assign variables for these unknowns.
Let
x be the amount received by the first friend
y be the amount received by the second friend
z be the amount received by the third friend
Next, we formulate equations for the relationships
x = 4z
z = 4y
x + y + z = <span>$231,000
Solving simultaneously,
4(4y) + y + 4y = </span><span>$231,000
21y = </span><span>$231,000
y = $11,000
z = 4($11,000) = $44,000
x = 4($44,000) = $176,000</span>
