Yes it is more than 20% because 20% would only total $15

3.00/12.50 = .24
This means the tip was 24% so it was more than 20%.

I NEEEEEED HEEEEEEEP PLZZZZZZZZ
Tema [17]

So, since the student makes $30 each week, we can disregard the number of hours.


So, we can model this situation by the following equation

9.5h+30


So, if he works 10.25 hrs (15 minutes = .25 of 1 hr) we just plug that number in

9.5h+30\\9.5(10.25)+30\\127.275

Since it's money we round to the nearest cent

So he will make $127.28 Next week

<h3>Answer:  -19, -15, -9, -1, 9   (choice A)</h3>

===================================================

Explanation:

If we plug in x = -2, then we get,

y = x^2 + 7x - 9

y = (-2)^2 + 7(-2) - 9

y = 4 - 14 - 9

y = -10 - 9

y = -19

So x = -2 leads to y = -19. The answer is between A and D.

---------

If you repeat those steps for x = -1, then you should get y = -15

Then x = 0 leads to y = -9

x = 1 leads to y = -1

Finally, x = 2 leads to y = 9

The outputs we get are: -19, -15, -9, -1, 9 which is choice A

Choice D is fairly close, but we won't have a second copy of -15, and  we don't have an output of -19.
