For this case we have the following expression:

9r + 3r ^ 2 - 5r + 7

We must simplify the expression.

To do this, we combine similar terms.

We have then:

3r ^ 2 + 9r - 5r + 7

Rewriting we have:

3r ^ 2 + 4r + 7

Answer:

The simplified expression is given by:

3r ^ 2 + 4r + 7

The original price is $60.The sales price is $45. What is the percent of discount?
MariettaO [177]
Hey there!

To start, first subtract 45 from 60 to find the amount of money taken off from the discount:
60-45
=15

Because 15 dollars have been taken off the original price, you can find the percent of discount by setting up this proportion where x represents the percent of discount:
15/60=x/100

Now, cross multiply and solve for x:
1500=60x
x=25

Therefore, your discount would be 25%.

Hope this helps and have a marvelous day! :)
