The term "a number" is going to be our variable, and we will use x to express that unknown number. The term "of" can also mean multiply, so.....

One fifth of a number = 1/5x

Three times the number = 3x

Twice the number = 2x

Now we add the other components to complete the rest of the equation:

1/5x + 3x = 2x +42

And then simplify the equation which comes down to:

x = 35

skad [1K]

Answer: Salid should get $38.75 of change.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • <em>Quantity of window trim bought: 35 feet </em>
  • <em>Cost per feet: $1.75 </em>
  • <em>Amount paid: $100 </em>

First, we have to calculate the total cost, by multiplying the Quantity of window trim bought (35) by the price per feet (1.75)

35 x 1.75 = $61.75

Finally, to calculate the change that Salid should get, we have to subtract the total cost (61.75) to the amount paid (100)

100-61.75=$38.75
