Camille started a pet service business for the summer. She washes dogs during the day and walks dogs in the evenings. However, Camille can walk only a maximum of 5 dogs in an evening. Her charges for each service are shown. - $8 per dog for a wash - $12 per dog for a walk Camille wants to work enough in one day to buy a new camera for $100. Which system of equations represents this situation, where x is the number of dogs she washes and y is the number of dogs she walks?

• y ≥ 5 8x + 12y ≥ 100

• y ≤ 5 8x + 12y ≤ 100

• y ≤ 5 8x + 12y ≤ 100

• y ≤ 5 8x + 12y ≥ 100
