Question: The cost per day of Kitty Kare cat sitters is $21.00 plus $9.00 per cat. Furbaby Sitters charge $26.00 and $4.00 per cat. Cameron is going out of town for two days and needs a sitter for his three cats. How much money does Cameron save by choosing Furbaby Sitters instead of Kitty Kare?

Answer:  $20.00

Solution:  Since Cameron has three cats, Kitty Care costs $21.00 + $9.00 × 3 = $48.00 per day. Furbaby Sitters costs $26.00 + $4.00 × 3 = $38.00 per day. That means that Kitty Care would cost Cameron $48.00 – $38.00 = $10.00 more per day. So, Cameron saves $10.00 × 2 = $20.00.
