The quick way to do this is to multiply the bill by 1, mult. it again by 0.18, and then add the two results together.
Better and faster: Mult. the bill amount ($42.75) by 1.18:
1.18($42.75) = $50.45 (answer)

Answer:
x = 24.27385%
Step-by-step explanation:
We can say 96.4x=23.4
Divide by 96.4: (x=23.4/96.4) = 0.24273858921
x=0.24273858921 so x = 24.27385...%
If you use the distributive property on (x+y)/3, the result should be:
(x/3) + (y/3)
Let x = cost of the dishwasher.
The amounts the children are paying are:
Mark =20% = 1/5, so 1/5x
Sorin = 75
Raymond = 1/4x
Stephanie = 75
Kristin = 1/3x
Add them together:
x = 1/5x + 1/4x + 1/3x + 75 + 75
x - ( 1/5x + 1/4x + 1/3x ) = 150
Rewrite fractions with common denominator:
x - ( 12/60x + 15/60x + 20/60x ) = 150
60/60x - 47/60x = 150
13/60x = 150
x = 150/1 • 60/13
x = 9000/13
x = 692.31
The total cost of the dishwasher is $692.31
Now calculate the amount each child pays:
Mark = 1/5 x = 692.31/ 5 = $138.46
Sorin = $75.00
Raymond = 1/4 x = 692.31 / 4 = $173.08
Stephanie = $75.00
Kristin = 1/3 x = 692.31 / 3 = $230.77
