<u>Answer:</u>
16.4%
<u>Step-by-step explanation:</u>
We know that a station charges $15.95 for a lubrication job and as a promotion sell six coupons were sold for lubrication jobs for $80.
We are to find the percentage discount that was being offered on purchase of 6 coupon lube book.
Original price of 6 coupons = 6 × 15.95 = $95.7
Difference in prices = 95.7 - 80 = $15.7
Percentage discount = 15.7/95.7 = 16.4%
Answer:
vertex form.f(0+x)+7 -y(-6 +y)-2
Step-by-step explanation:
this is what I understand it about
<u>So the equation to find the sum of interior angles is 
, with n = number of sides.</u> In this case, this is an octagon (8 sided polygon), so plug in 8 into the equation to solve:
<u>The sum of the interior angles is 1080°</u>
It should be 30.4
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.
I hope this helps!
