Final answer:
Mang Ben needs an additional 15.79 meters of cloth to make a bag for his son, as he has 89.96 meters but requires a total of 105.75 meters.
Step-by-step explanation:
The question asks how many more meters of cloth Mang Ben will need to complete a bag if the total material required is 105.75 meters and he currently has 89.96 meters.
To solve the problem, subtract the amount of cloth Mang Ben currently has from the total amount of cloth needed. The calculation is as follows:
- Determine the total amount needed: 105.75 meters.
- Subtract the amount Mang Ben has: 89.96 meters.
- Perform the subtraction: 105.75 meters - 89.96 meters = 15.79 meters.
Therefore, Mang Ben needs an additional 15.79 meters of cloth to complete the bag.
