I would say C, because it makes the most sense
Answer:
see the explanation
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
Step-by-step explanation:
Let
x ---> the number of hot dogs that were sold
y ---> is the number of sodas that were sold
we know that
You sold a total of 90 hot dogs and sodas combined
so
----> equation A
You made a total of $105
so

isolate the variable y
----> equation B
substitute equation B in equation A

solve for x

Find the value of y (equation B)

therefore
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
Number twenty-one is one and three-fourths
8x + 3c = 2200
11xc= 2200
2200÷11
200
200xc
