Answer:
The cost of a piece of dark meat is $0.70 and the cost of a piece of white meat is $0.85.
Step-by-step explanation:
Given:
At Clucker's Chicken, a bucket of 4 pieces of dark meat and 5 pieces of white meat costs 7.05.
A bucket of 3 pieces of dark meat and 8 pieces of white meat costs 8.90.
Now, to find the cost of a piece of dark meat and the cost of a piece of white meat.
Let the cost of a piece of dark meat be [tex]x.[/tex]
And the cost of a piece of white meat be [tex]y.[/tex]
A bucket of 4 pieces of dark meat and 5 pieces of white meat costs $7.05.
So,
[tex]4x+5y=7.05[/tex]
[tex]4x=7.05-5y[/tex]
[tex]x=\frac{7.05-5y}{4}[/tex] .......(1)
Now, a bucket of 3 pieces of dark meat and 8 pieces of white meat costs $8.90.
[tex]3x+8y=8.90[/tex]
Substituting the value of [tex]x[/tex] from equation (1) we get:
[tex]3(\frac{7.05-5y}{4})+8y=8.90[/tex]
[tex]\frac{21.15-15y}{4} +8y=8.90[/tex]
[tex]\frac{21.15-15y+32y}{4} =8.90[/tex]
Multiplying both sides by 4 we get:
[tex]21.15-15y+32y=35.60[/tex]
[tex]21.15+17y=35.60[/tex]
Subtracting both sides by 21.15 we get:
[tex]17y=14.45[/tex]
Dividing both sides by 17 we get:
[tex]y=0.85[/tex]
The cost of a piece of white meat = $0.85.
Now, substituting the value of [tex]y[/tex] in equation (1) we get:
[tex]x=\frac{7.05-5y}{4}[/tex]
[tex]x=\frac{7.05-5\times 0.85}{4}[/tex]
[tex]x=\frac{7.05-4.25}{4}[/tex]
[tex]x=\frac{2.8}{4}[/tex]
[tex]x=0.70.[/tex]
The cost of a piece of dark meat = $0.70.
Therefore, the cost of a piece of dark meat is $0.70 and the cost of a piece of white meat is $0.85.
