Answer:
The cost per duck is $5.00 and $8.00 for chickens
Step-by-step explanation:
The equation would be like this:
50c + 30d = 550 (divide this by 10)
5c + 3d = 55
3d = 55 - 5c (multiply by 3)
9d = 165 - 15c
Next,
44c + 36d = 532 (divide this by 4)
11c + 9d = 133
11c + 165 - 15c = 133
11c - 15c = 133 - 165
-4c = -32 (divide by -4)
c = 8
Therefore, the cost of each chicken is $8.00
9d = 165 - 15c
9d = 165 - 15(8)
9d = 165 - 120
9d = 45 (divide by 9)
d = 5
Answer:
1 3/4
Step-by-step explanation:
2/8 * 7
2/8 will simplify
Divide the top and bottom by 2
12/8 = 1/4
1/4*7
7/4
We need to change this from an improper fraction to a mixed number
4 goes into 7 once with 3 left over
1 3/4
