Carla paid an amount of 30 for 3 items.
Step-by-step explanation:
Given:- Carla bought,
3 packages of hamburger at price of 7.95 per package.
1/4 pound of tomatoes at price of 2.96 per package.
1 package of cheese at price of 4.25
Received amount = 1.16
To find:- Paid amount=?
Solution:-
Carla bought 3 packages of hamburger at price of 7.95 per package,
So, cost of 3 packages will be
Cost of 3 packages of hamburger =
Cost of 3 packages of hamburger = 23.85 ---------------(1)
Carla bought 1/4 pound of tomatoes at price of 2.96 per package,
So, cost of 1/4 pound of tomato is,
Cost of 1/4 tomato = 
Cost of 1/4 tomato = 0.74 ---------------(2)
Carla bought 1 package of cheese at price of 4.25,
Cost of 1 package of cheese = 4.25 ---------------(3)
Now,
Total price of 3 items = 23.85+0.74+4.25 ------------(from 1,2,3)
Total price of 3 items = 28.84 -------------------(4)
Now,
Paid amount = Total price of 3 items + Received amount
Paid amount = 28.84+1.16 --------(from 4 and given)
Paid amount = 30
Therefore Carla paid an amount of 30 for 3 items.
