Answer:
126 inches

To express the total length of ribbon convert the three lengths into the same measurement of inches.
Carol has 42 inches.
Tina has 2.5 feet which is equal to 24+6=30 inches.
Baxter has 1.5 yards which is equal to 36+18 =54 inches.
This means in total there is 42 + 30 + 54= 126 inches
