Answer:
sorry im not sure about the answer but this is how you figure it out
Step-by-step explanation:
50a+30b=550
after you simplify = 5a+3b=55
44a+36b=532
after you simplify=11a+9b=133
then you try to find a number
5a+3b=55
then you have to find different possibilities of a and b and if it can fit into both equations then it is correct
Answer: each chicken costs $8.
Each duck costs $5
Step-by-step explanation:
We want to determine the amount for each chicken and each duck.
Let x represent the cost per chicken.
Let y represent the cost per duck.
Last month, he sold 50 chickens and 30 ducks for $550. This is expressed as
50x + 30y = 550- - - - -- - - - - - 1
This month, he sold 44 chickens and 36 ducks for $532. This means that
44x + 36y = 532- - - - - - - - - - - - - 2
Multiplying equation 1 by 44 and equation 2 by 50, it becomes
2200x + 1320y = 24200
2200x + 1800y = 26600
Subtracting, it becomes
- 480y = - 2400
y = - 2400/ - 480
y = 5
Substituting y = 5 into equation 1, it becomes
50x + 30 × 5 = 550
50x + 150 = 550
50x = 550 - 150 = 400
x = 400/50
x = 8
