The sales price of machine is $ 748
<em><u>Solution:</u></em>
Given that,
Original price of machine is $ 850
Discount rate = 12 %
To find: discount amount and sales price of machine
<h3><u>Find the discount amount:</u></h3>Given that discount rate is 12 % , which means 12 % of original price of machine
Discount amount = 12 % of original price of machine
Discount amount = 12 % of 850

<h3><u>Find the sales price of machine</u></h3>Sales price = Original price - Discount amount
Thus the sales price of machine is $ 748
Answer: B
<u>Step-by-step explanation:</u>
the average rate of change is the same as slope (m). Calculate the slope between the beginning and ending coordinates for each stage.
A = (0, 1) → (4, 2.5)
B = (4, 2.5) → (6, 4)
C = (6, 4) → (8, 6)
D = (8, 6) → (10, 9)
E = (10, 9) → (12, 14)
<u>Stage A</u>
=
= 0.375
<u>Stage B</u>
=
= 0.75
<u>Stage C</u>
=
= 1.00
<u>Stage D</u>
=
= 1.5
<u>Stage E</u>
=
= 2.5
(A) Stage B = Stage C False
(B) Stage A is the slowest TRUE
(C) Stage D > Stage E False
(D) Stage D is the fastest False
