<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

Answer:
12
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 9)² + (y - 4)² = 36 ← is in standard form
with r² = 36 ⇒ r = 
= 6
diameter = 2 × r = 2 × 6 = 12
