The art teacher had 1,321 pipe cleaners for a project. She used 477 with the entire fourth grade. A parent donated 2,600 pipe cleaners. How many pipe cleaners does she have now?

3,444

Step-by-step explanation:

The art teacher had 1321 pipe cleaners for a project

She used 477 with the fourth age

A parent donated 2,600 pipe cleaners

Therefore the number of pipe cleaners she have left can be calculated as follows

= 1321-477+2600

= 844 + 2600

= 3,444
