Hearing Protection

When you wear ear plugs NRR around 30 and an electronic hearing muff NRR about 22 will that yield a NRR of 52 or is it more complicated than that? My wife and I will be shooting pistols (380 & 45)at an indoor range and want to keep the hearing we have left.
What is the best for the money electronic hearing muff?
Thanks,
Bill
