If a bored game was originally $25 and it is on sale for $18 , what is the percent discount?
Blizzard [7]
Hi there!

To find the percent discount, we need to divide the new price by the original price without the discount:

18 / 25 = 0.72

Now, we convert this into a percentage, so we can find the <em>percent </em>discount:

0.72 = 72%

Now, we subtract from 100%:

100% - 72% = 28%

So, the answer is 28%. 

Hope this helps!

10a + 6b + 6c<br>It needs to be simplified <br>I also need the steps​
irinina [24]

\Large\boxed{\tt Answer:~2(5a+3b+3c)}

\tt Step-by-step~explanation:

You cannot simplify this expression, but instead, you can factor it like this:

Find the Greatest Common Factor (GCF) of the three numbers.

\tt 10 \div 5=2\\6 \div 3 = 2\\6 \div 3 = 2\\GCF=2

Since the GCF is 2, we can factor 10, 6, and 6 by dividing them by two and placing them inside parenthesis.

\tt 2(5a+3b+3c)

When you multiply 2 to each of the terms, you would end up with 10a + 6b + 6c.
