Answer:

Step-by-step explanation:
You can solve this equation with the quadratic formula which is:

All you need to do is rearrange the equation (add
to both sides and then multiply both sides by 2) to get:

From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:

That simplifies to:

Which simplifies even further to:

Which gets you:

P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.
P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
multiply 300 by 7 and then you should be able to finish the equation
