Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs
Answer:
634 steak sandwiches
h = hot dogs
s = steak sandwiches
First, lets make 2 equations.
2.95h + 9.95s = 7343.75
h + s = 985
We can make the second equation h = 985 - s
Now substitute h into the first equation.
2.95(985 - s) + 9.95s = 7343.75
Distribute the 2.95
2905.75 - 2.95s + 9.95s = 7343.75
Simplify s
2905.75 + 7s = 7343.75
Subtract 2905.75 from both sides
7s = 4438
s = 634
If h = 985 - s and s = 634 we can find h by subtracting 634 from 985
985 - 634 = 351
Now to check:
351 times 2.95 = 1035.45
634 times 9.95 = 6308.3
6308.3 + 1035.45 = 7343.75 so that means our answer is correct.
