Does your baby still take your breastmilk even when you formula feed?

The reason for my question is because I want to try to formula feed my baby and breast feed. Due to the fact that when I pump milk I don’t get much out as too when she latched on me she gets more. I will only feed baby formula Milk while I’m at work so she won’t be on it for to long plus I will only be working part time.I want to start working because I need to make ends meet 😞 since hubby is the only one working he needs a helping hand. I was wondering if your baby will still take your breast milk even when you formula feed ?
