Answer:
The expression for the cost of soda is 100 ×
cents
Step-by-step explanation:
Given as :
The quantity of hot dogs sold by vendor = h
The quantity of sodas sold by vendor = s
The total cost of hot dogs and soda = $ d
Let The price of hot dogs = $ x
And The price of soda = $ y
Now, According to question
The price of hot dogs is twice as much as soda
so, $ x = 2 × $ y
I.e x = 2 y
and $ x h + $ y s = $ d
Or , 2 × $ y h + $ y s = $ d
Or, y = 
∵ 1 dollar = 100 cents
So, the price of
= 100 ×
cents
Hence The expression for the cost of soda is 100 ×
cents Answer
