To find:
The number of flocks of chicks can the class buy.

Answer to Problem 27E
The number of flocks of chicks can the class buy is 12
Explanation of Solution
Given information:
The class has raised $755 for a hunger relief organisation. The organization provides farm animals that people can use to produce food. Your class plans to buy animals for a family recovering from an earthquake.
One heifer costs $500, each and one flock of chick costs $20.
Calculation:
Total budget of the class is $755
A young cow or heifer costs $500.
Therefore,
The class took a heifer costs $500
So, the remaining balance left-
each and one flock of chick costs $20
so, the class can only take 12 flock of chick
One pig costs $120 each.
The class also buys a heifer costs $500.
So, the class is left with
Therefore,
The number of pigs class can buy is 2.
After buying a heifer and pigs the class will be left with
So, the class doesn’t have money to buy a flock of chick as because one flock of chick costs $20 and the class is only left with $15 as balance.
To find:
The number of pigs the class can buy.

To find:
Does the class have enough money to buy a flock of chicks?

Answer to Problem 27E
No, the class doesn’t have enough money to buy a flock of chicks.
Explanation of Solution
Given information:
The class has raised $755 for a hunger relief organisation. The organization provides farm animals that people can use to produce food. Your class plans to buy animals for a family recovering from an earthquake.
If class buys both heifer and pigs does it have a lot of money to buy a flock of chick?
Calculation:
After buying a heifer and pigs the class will be left with
So, the class doesn’t have money to buy a flock of chick as because one flock of chick costs $20 and the class is only left with $15 as balance.
