Please help with question

Step2247 [10]

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
