A cleaning company charges $3 per square foot and a flat fee of $100. Which of the equations below shows the cost y, in dollars,
LekaFEV [45]

Step-by-step explanation:

Y= 3x + b

As, to know the total, which is y, we need to solve for the cost

So first for money per square foot = $3

For square foot = x

So, price for x square foot = $3x (here this is the value of m)

Now, for value b,

$100 is added to the cost as its the charge, as the flat fee

So the value of b = $100

So, y=3x+100
