5 answers

The sale price of the XBOX 360 is $319.20.

To find this, you can start by calculating what 20% of $399 is:

$399 x 0.20 = $79.80

This represents the discount that is being applied to the regular price. To get the sale price, you need to subtract the discount from the regular price:

$399 - $79.80 = $319.20
Amber's birthday party will cost $12 if she invites 4 guests. If there are 7 guests, how much will Amber's birthday party cost (c)? Assume the relationship is directly proportional.
We can use a proportion to solve the problem:

12/4 = c/7

To solve for c, we can start by cross-multiplying:

4c = 12 x 7

Then, we can simplify:

4c = 84

Finally, we can solve for c by dividing both sides by 4:

c = 21

Therefore, Amber's birthday party will cost $21 if she invites 7 guests.
