How many bottles a day are your formula fed babies getting?

My baby will be 3 months old July 1st and eats 6oz about every 4 hours starting around 7am and ending around 7pm. So 4 bottles totaling 24oz all day. She sleeps through the night with no feedings. She seems satisfied but I just saw online 3 month olds should have about 35oz a day. Now my baby is just hitting 10 1/2 pounds now so she is smaller but am I starving my baby?! Ps we have an appointment with pediatrician Friday and will discuss just trying to get a feel for others experiences.
