Answer:
The answer to your question is the big dog weighs 120 pounds
Step-by-step explanation:
Data
big dog = b
medium dog = m
small dog = s
Equations
b = 5s
m = 12 + s
s = 2/3 m
Process
1.- Substitute m in the last equation
s = 2/3(12 + s)
s = 24/3 + 2/3s
s - 2/3s = 8
1/3 s = 8
s = 8(3)
s = 24 pounds
2.- Substitute s in the first equation
b = 5(24)
b = 120 pounds

Original cost of the necklace = $28
Percentage by which the store reduces the price of the necklace = 20%
Amount of discount given
by the store on the necklace = (20/100) * 28
= 28/5 dollars
= 5.6 dollars
So
The price of the necklace after discount = (28 - 5.6) dollars
= 22.4 dollars
Amount of discount on coupon = $2
Then
Price of the necklace after deducting coupon discount = (22.4 - 2) dollars
= 20.4 dollars
So Janet will pay 20.4 dollars for the necklace.
