Thanks for your help, but I'm still a little confused, can you please explain where the 1.64 [2.65+1.64*0.35] comes from and why should I multiply it by the standard deviation?? Is it a formula, I should know?

The formulat does not make sense, you must have copied it wrong. Otherwise, this is standard basic statistics.

The 95th percentile of a standard normal distribution is 1.644853. That's where the 1.64 comes from.
