Step-by-step explanation:
y = total number charged.
x = number of animals vaccinated.
If she charges $20 as a base, this means it is a constant value.
She also charges $10 for each animal vaccinated, this can be written as 10x.
Therefore the equation for the total number charged (y) can be written as:
Total amount charged = $20 + $10 for every animal vaccinated.
y = 20 + 10x
