Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus $1 per hour. Which equation could you use to see when the two companies would charge the same amount? Options:

18x = 22x

,

3x + 15 = x + 21

,

15x + 3 = 21x + 1

,

3x + 15 + 21x = 1

Back

3x + 15 = x + 21
