Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.
Let x be the cost of dryer, y be the cost of washer
x + y =821
x-79 = y
combine 2 equation
we got
x + (x-79) = 821
2x + 79 = 821
2x = 742
x=471
The cost of dryer is $471

Step-by-step explanation:
3-16/a= 5
subtract 3-16
-13/a=5
multiply both sides by a
-13=5a
flip the equation
5a= -13
divide both sides by 5
a= -2.6
check the equation
3-16/-2.6=5
-13/-2.6=5
5=5
