Answer:
The number of DVD's is 6.
Step-by-step explanation:
Given:
Grace bought a television for $329.
Some DVDs for $5.75 each.
She spent total of $363.50
Now, to find out the number of DVD's Grace bought.
Let the number of DVD's be [tex]x.[/tex]
So, cost of DVD's =[tex]5.75x[/tex]
Cost of television = $329.
Total amount spent = $363.50.
According to question:
Now, putting the equation to solve:
[tex]329+5.75x=363.50[/tex]
Subtracting with 329 on both sides we get:
[tex]5.75x=34.50[/tex]
Dividing both sides by 5.75 we get:
[tex]x=6.[/tex]
Therefore, the number of DVD's is 6.
