$256/4 hrs = 64 hrs
3 hrs x $64 = $192
2 hrs x $64 = $128
$256 + $192 + $128 = $576
Or
(4+3+2) x $64 = $576
9 x $64 = $576

Hello! :)
Let one number be equal to x.
Since the other is 12 more, we can express this as x + 12.
Write an expression showing the sum of these two numbers equal to 40:
x + (x + 12) = 40
Combine like terms:
2x + 12 = 40
Subtract 12 from both sides:
2x = 28
Divide both sides by 2:
x = 14
This is the value of one of the numbers. Since the other number is "x + 12", we can solve for this value:
14 + 12 = 26.
The two numbers are 14 and 26.
Answer:
360 and 60.
Step-by-step explanation:
Let Christopher earns x amount of money and y be money earned by Michael.
Firstly, Christopher has six times as much money as Michael so,
x=6y........ (i)
If Michael earns $80 and Christopher earns $60, Christopher will then have three times as much money as Michael so,
x+60=3(y+80)
From (i),
6y +60= 3(y+80)
3(2y+20)=3(y+80)
2y+20=y+80
2y-y=80-20
y=60
Substituting value of y in equation (i),
x=6×60=360.
Therefore, Christopher earned 360 and Michael earned 60.
