The function f(t) becomes
The manager wants to give free hamburgers to only 1% of her costumers, which means that probability of a costumer getting a free hamburger is 0.01
The probability that a costumer has to wait for more than x minutes is:

Take natural log on both sides
The costumer has to wait x = 11.53 mins ≅ 12 mins to get a free hamburger
Answer:
Charlotte spent on furniture
Step-by-step explanation:
Given:
Charlotte spent 25% more on furniture than she will on flooring
To Find:
Amount spent on furniture = ?
