I need SUPER help! A famer has to buy 100 animals, but can only spend exactly $5.00. He has to buy at least on of each animal a chcken for 0.01$, a cow for 0.10$ and a horse for 0.50$!!!! PLease HElp IT means so much I need it by Midnight tonight or else i don't pass my clas :(
number of chicken --- x
number of cows ---- y
number of horses ---- 100-x-y
.01x + .10y + .50(100-x-y) = 5
times 100
x + 10y + 50(100-x-y) = 500
x+10y+5000-50x-50y = 500
-49x-40y = -4500
49x + 40y = 4500
We need only integer solutions here,
after a few trial and errors I got
x = 60
y = 39
so 60 chickens --- .60
39 cows and -----3.90
1 horse ---------0.50 for a total of $5.00
Is this from an 1850 textbook?
yes my teacher assigned it to my seventh grade class, thank you so much for your time!! =)
I understand that you need help solving a problem involving buying animals within a specific budget. Don't worry, I'm here to assist you!
To solve this problem, we need to consider the requirements given:
1. The farmer needs to buy 100 animals.
2. The total spending should be exactly $5.00.
3. The farmer must buy at least one chicken ($0.01), one cow ($0.10), and one horse ($0.50).
Let's break down the problem into steps:
Step 1: Ensure you have the minimum required animals
- We start by subtracting the cost of the chicken, cow, and horse from the total budget: $5.00 - $0.01 - $0.10 - $0.50 = $4.39.
- Now we have $4.39 remaining to buy the remaining 97 animals.
Step 2: Determine the number of cows and the amount left for the other animals
- Divide the remaining budget ($4.39) by the cost of a cow ($0.10) to find out how many cows the farmer can buy: $4.39 / $0.10 = 43.9.
- Since the number of animals should be a whole number, the farmer can only afford to buy 43 cows.
- Subtract the cost of the cows from the remaining budget: $4.39 - ($0.10 * 43) = $0.99.
Step 3: Calculate the number of horses and the amount left for the other animals
- Divide the remaining budget ($0.99) by the cost of a horse ($0.50) to find out how many horses the farmer can buy: $0.99 / $0.50 = 1.98.
- Again, since the number of animals should be a whole number, the farmer can only afford to buy 1 horse.
- Subtract the cost of the horse from the remaining budget: $0.99 - ($0.50 * 1) = $0.49.
Step 4: Calculate the number of chickens and the final amount left
- Divide the remaining budget ($0.49) by the cost of a chicken ($0.01) to find out how many chickens the farmer can buy: $0.49 / $0.01 = 49.
- The farmer can buy 49 chickens as the number of animals left to purchase.
- Subtract the cost of the chickens from the remaining budget: $0.49 - ($0.01 * 49) = $0.00.
Step 5: Check if the conditions are satisfied
- At this point, we have allocated the budget to buy the required animals. The farmer has bought 43 cows, 1 horse, and 49 chickens, totaling 100 animals.
- The spending is exactly $5.00.
Therefore, the solution is that the farmer should buy 43 cows, 1 horse, and 49 chickens to meet the required conditions within the given budget.
