Given :
Initial length of electric cable needed, .
Later, Sally is told that the homeowner has decide to cut back from a three-car garage to a two-car garage, which will eliminate two branch circuits, one of 23 feet and the other of 34 feet.
To Find :
How many feet of wire will be needed now.
Solution :
Wire needed is given by :
Required = Total wire - ( length of 1nd branch + length of 2nd branch )
Required = 550 - ( 23 + 34 )
Required = 550 - ( 57 ) ft
Required = 443 ft
Therefore, length of wire required is 443 ft.
Hence, this is the required solution.
The unit rate per munchkin is $0.22.
<h3>What is Division?</h3>
Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
The cost of 25 munchkins cost $5.46, therefore, the unit rate of each munchkin can be written as,
Hence, the unit rate per munchkin is $0.22.
