Rachel is a veterinarian. She charges $20 as a base and $10 for each animal that she vaccinates. Let x be the number of animals vaccinated and y be the total amount charged. Write the equation.

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
