3.49 rounded is 3.5
9.78 rounded is 10
6.18 rounded is 6

2 + 1 + 3.5 + 10 + 6 = 22.5

Answer:

Total cost of items is $22.5.

Step-by-step explanation:

Rounding off is a kind of estimating. When the number after decimal is less than 5, the last figure should be unchanged, but the number after decimal is 5 or more than 5 add one to the last digit.

1.85 ≈ 2

0.98 ≈ 1

3.49 ≈ 3.5

9.78 ≈ 10

6.18 ≈ 6

Total cost of items = 2 + 1 + 3.5 + 10 + 6 = $22.5
