Hope it will help you :)
Step-by-step explanation:
Let the price of a hot dog be h and price os a soda be s dollars. Then we have:-
4h + 3s = 6.55.......................(1)
2h + 5s = 4.85 multiply this equation by -2:-
-4h -10s = -9.70......................(2)
Adding (1) and (2):-
-7s = -3.15
s = -3.15 / -7 = 0.45
So $0.45 is the price of a soda
To find price of a hot doe plug s = 0.45 into equation (1):-
4h = 3(0.45) = 6.55
4h = 6.55-1.35 = 5.20
h = 5.20 / 4 = $1.30
The answer is price hot dog = $1.30
