Answer: B. y = 5x + 10
Step-by-step explanation:
Based on the scenario in the question, you didn't really say what you'll like to calculate but I guess you want to know the equation that can be used to represent the above information.
Let x = the number of children babysit
The amount charged by Sandy can then be written as:
y = 10 + 5(x)
y = 10 + 5x
y = 5x + 10
Therefore, the correct option is B.
