Alemonade stand sells lemonade for 1.50 a cup. the actual cost is 25 cents per cup. the profit is what portion of selling price?

The profit is    of the selling price

Step-by-step explanation:

We need to find what "fractional amount" is the profit of the Selling Price.

We can first see:

Profit = Selling Price - Cost

Given,

SP (Selling Price) = 1.50

Cost = 0.25

Profit = 1.50 - 0.25 = 1.25

Now,

Profit = 1.25

SP = 1.50

We find the fractional amount (what portion) of profit with respect to SP by dividing. Shown below:

1.25/1.50 =

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
