41 yards is correct

Step-by-step explanation:

Step 1. The information we have is:

Originally Jane had $25 on her debit card.

She made a purchase of bulk ribbon for 21 cents per yard.

And after that she ended up with $16.39 on the card.

Step 2. Make an equation to describe the situation.

The equation that describes this situation is:

Where 25 is the initial amount and to that, we subtract 0.21y, where y is the number of yards that she bought of ribbon. And all of this has to be equal to the final amount of 16.39.

Step 3. Solve the equation for y:

To solve for y, we subtract 25 to both sides of the equation:

⇒

⇒

Then, divide both sides of the equation by -0.21:

The result is:

The answer is 41 yards of ribbon.

the answer is 4.8 units on e2020.
