Work the following financial transactions. your station charges $15.95 for a lubrication job. as a promotion you sell six coupons for lubrication jobs for $80. what percentage discount are you offering for customers who purchase the 6-coupon lube book? discount (to the nearest tenth) =

16.4%

Step-by-step explanation:

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%

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

7

step-by-step explanation:

the answer would be 7
