jhon needs 10 meters of lace for the table cover. He has 3.8 meters of red lace and 2.4 blue lace. How much lace does he need more?

First we have to add the number of laces he has now which is 3.8 + 2.4 = 7.2 meters

Then we subtract it from the total amount needed for the table that is 10 – 7.2 = **2.8 meters.**

Please mark brainliest or thanks if it helped!

Let n be the total length of red and blue laces.

Let t be the needed length of lace.

Given:

3.8 m lace of red

2.4 m lace of blue

Need 10 m

Equation:

3.8 m + 2.4 m = n

10 m – n = t

Solution:

3.8 m + 2.4 m = 6.2 m

10 m – 6.2 m = 3.8 m

Answer:

Therefore, **3.8 m** is still needed.
