times = int(input("How many times a week do you eat at the student cafeteria? "))
price = float(input("The price of a typical student lunch? "))
groc = float(input("How much money do you spend on groceries in a week? "))

print("Average food expenditure:")
print (f"Daily: {times * price + groc / 7} ")

puts out:

How many times a week do you eat at the student cafeteria? 4
The price of a typical student lunch? 2.5
How much money do you spend on groceries in a week? 28.5
Average food expenditure:
Daily: 14.071428571428571 I need it to be 5.5 not 14.07

You have a precedence problem.

In arithmetic expressions, multiplication and division happen before addition. So this:

times * price + groc / 7

divides groc by 7 and then adds it to the result of multiplying times by price. You want instead to divide the whole value tiems * price + groc by 7, which means you need parentheses:

(times * price + groc) / 7

Well, for the daily output just use parentheses. Like simple math, ((times*price)+groc)/7 and I'm pretty sure this will do.

As for the weekly if I'm getting this right, just do this, weekly = (daily * 7) again, if you are doing this directly use parentheses.
