Using front end estimation, we round to the nearest ten, so 13 rounded to the nearest ten is 10, 26 to the nearest ten is 30, and 22 to the nearest ten is 20. We add 10 + 30 + 20 to get 60. --- Hope this helps!
Hello! So for this question, all you have to do is add the numbers up to get the total cost. Groceries were $102.34 and the new shoes were $53.36. 102.34 + 53.36 = 155.7. Lorena spent $155.70 total.
