Step-by-step explanation:

so, she spent 25-16.39 = $8.61 on the ribbon.

1 yard of the ribbon costs $0.21.

how many yards did she buy with that amount of money ?

well, as many times as 0.21 fits into 8.61 :

8.61 / 0.21 = 41

so, she bought 41 yards of ribbon.

Answer:

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:

[tex]\tt 25-0.21y=16.39[/tex]

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:

⇒ [tex]\tt-0.21y=16.39-25[/tex]

⇒ [tex]\tt -0.21y=-8.61[/tex]

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

[tex]\tt y=\frac{-8.61}{-0.21}[/tex]

The result is:

[tex]\tt y=41[/tex]

The answer is 41 yards of ribbon.

Hope this helps you!

Have an awesome day! :)
