During his last 5 jobs, an electrician used the following amounts of cable:

12.995 m

7.505 m

10.08 m

6.95 m

9.75 m

By rounding each amount to 1 decimal place, what was the total amount of cable used?

The total amount of cable used is 47.4m

Explanation:

Given:

Amounts of cable used that has to be rounded off to 1 decimal place:

12.995 m ≈ 13.0 m

7.505 m ≈ 7.5m

10.08 m ≈ 10.1 m

6.95 m ≈ 7.0 m

9.75 m ≈ 9.8 m

Total amount of cable used = 13m + 7.5m + 10.1m + 7m + 9.8m

= 47.4m

Therefore, total amount of cable used is 47.4m
