Answer:

-9

Step-by-step explanation:

We are summing the 3rd 4th and 5th terms because k goes from 3 to 5

The third term is

-2(3) +5 = -6+5 = -1

The fourth term is

-2(4) + 5 = -8+5 = -3

The fifth term is

-2(5) +5 = -10 +5 = -5

Add these 3 terms together

-1+-3+-5 = -9

For some math loving friends ​
shtirl [24]

The first step of finding the percent tip, we must find how much tip she paid:

     Tip = $38.61 - $33 = $5.61

To find the percent tip, we must divide the tip amount by the amount she paid before the tip

     $5.61 / $33 = 0.17 --> 17%

Thus the percent tip is 17%

Hope that helps!
