To solve this problem you must apply the proccedure below:
1. Let's call:
x: hot dogs.
y: hamburguers.
2. Then, you must make a system of equations, as below:
5x+4y=12.25 (i)
4x+5y=12.50 (ii)
3. Now, you can solve the system of equation as below:
5x+4y=12.25
x=(12.25-4y)/5
4x+5y=12.50
4((12.25-4y)/5)+5y=12.50
y=1.5
4x+5y=12.50
4x+5(1.5)=12.50
x=1.25
4. Therefore, the answer is:
The cost of one hot dog is $1.25 and the cost of one hamburguer is $1.50
Answer:
12
Step-by-step explanation:

Answer:
Final Price = $385.60
You save = $96.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 482 × 20/100
Discount = 482 x 0.2
You save = $96.40
Final Price = Original Price - Discount
Final Price = 482 - 96.4
Final Price = $385.60
Answer:
Step-by-step explanation:
In both cases we have a two-term expression. In each case, determine what the greatest common factor is and then use it to factor the expression:
144t - 36 = 36(4t - 1)
8x - 12 = 4(2x - 3)
Step-by-step explanation:
A.) Ok, so the mean price for Southtown is 72,800.
And the mean price for middle town is 54,900
So Southtown has the higher mean price.
Explanation:
To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.
72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000
Then,
364,000/ 5 = 72,800
B.) It is 17,900
Explanation:
72,800 - 54,900 = 17,900
Hope this helps you out!!! : )
