Question

5. Marcie bought a 50-foot roll of packing tape. She used two 85-foot lengths. How much tape is left on the roll?​

Answer 1

Marcie has used a total of 170 feet of tape (two 85-foot lengths) from the 50-foot roll, which means that there is 50 - 170 = -120 feet of tape left on the roll, indicating that the roll is empty and there is no tape left.
