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

Answer: 
Step-by-step explanation:
The slope of the line is

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be 
2.5 = 2 5/10 as a Mixed fraction
To get a improper fraction, multiply the whole number with the denominator, and then add the numerator to the answer, giving the numerator (keep the denominator number)
2 x 10 = 20
20 + 5 = 25
25/10 is your answer

3/5 is used
2 1/2 gallons can be expressed as 5/2
1 1/2 gallons is the same as 3/2the fraction used is amount used over total amount
So (3/2)/(5/2) the 2 s cancel leaving you with 3/5
