Answer:

6 dollars

Explanation:

Lets say the price of a single hamburger is some variable h, and the price of a drink is some variable d. We can make a system of equations with the prices:

5h+d=17

2h+6d=25

Now, you can multiply the first equation by 6 to leave you with a new system of equations:

30h+6d=102

2h+6d=25

Subtracting the second equation from the first, you are left with:

28h=77

h=2.75

Plugging this back into the first equation gives:

5(2.75)+d=17

13.75+d=17

d=3.25

Now that you know the price of an individual hamburger and drink, you know that the total combined cost is:

h+d=2.75+3.25=$6
