Answers and Step-by-step explanation:
Trade Discount = List prices x Trade discount rate,
For 40% Trade discount rate,
TRADE DISCOUNT =
7000 x 40% = $2,800
For 20% Trade discount rate,
Net amount = 7000 - 2800 = 4200
TRADE DISCOUNT =
4200 x 20% = $840
For 15% Trade discount rate,
Net amount = 4200 - 840 = 3360
TRADE DISCOUNT =
3360 x 15% = $504
Therefore, the Trade Discount amounts are: $2,800, $840 and $504 for 40/20/15 rates respectively.

Answer:
6
Step-by-step explanation:
We have y ∝ x which is another way of saying y varies directly with x
We can rewrite the direct proportion relation y ∝ x as y = k.x where k is a constant - the constant of proportionality
So y = kx or x = y/k
using y and x values know, we can solve for k and then solve for any x given y
We have
y = 37.4 = k (17)
Therefore k = (37.4/17) = 2.2
To find x given y = 13.2, use the second equation
x = y/k = 13.2 / 2.2 = 6
