Answer: Our required linear equation would be 
Step-by-step explanation:
Since we have given that
Cost of deep fried bananas on a stick = $1.00
Number of sales reached = 100 per day
Cost of deep fried bananas on a stick becomes = $2.00
Number of sales reached = 52 per day.
Let x is the number of dollars each.
Let y be the number of vendors sale.
So, we need to form the linear equation:
As we know the formula for two point slope form:

Hence, our required linear equation would be
