Answer:
To find the cost of a hot dog and hamburger, we can set up a system of equations based on the information given. For example, let x be the cost of a hot dog and y be the cost of a hamburger. Then we have:
4x + 7y = 68 (equation 1)
7x + 3y = 67 (equation 2)
We can use substitution or elimination methods to solve the system of equations.
Substitution method:
Solve equation 1 for y in terms of x: y = (68 - 4x)/7
Substitute this expression into equation 2: 7x + 3((68 - 4x)/7) = 67
Simplifying and solving for x: 7x + 3(68 - 4x)/7 = 67
7x + 204 - 12x = 469
-5x = -401
x = 80
Substitute x = 80 back into equation 1: 4(80) + 7y = 68
320 + 7y = 68
7y = -252
y = -36
Therefore, the cost of a hot dog is $80, and the price of a hamburger is $-36 (which is not possible, it could be a typo or mistake in the given information)
