Donna receives a $100 gift card to MovieStop. Her Blu-ray player is able to play both Blu-rays and DVDS, so she would like to get a combination of both. Each Blu-ray cost $25.99 and DVDs cost $15.99 each.

Step 1
Value of gift card received by Donna=100$
Cost of one BlueRay=25.99$
Cost of one DVD=15.99$
Number of Blue-Ray purchased by Donna=b
Number of DVDs purchased by Donna=d
Cost of Blu-Ray's =25.99×b$
Cost of DVDs =15.99×d$
Step 2
Here, the cost of the total purchase including Blue-ray and DVDs must be equal to 100$.
Then, 25.99b+15.99d=100
Hence this is the required equation.
