Tommy bought a piece of ribbon and cut it into 3 pieces. The second piece was 2.9 m longer than the third piece. The first piece was 1.85 m shorter than the second piece.
- If the third piece was 12.15 m, find the length of the ribbon before it was cut.
- How much did Tommy pay if each metre of the ribbon was $8?
(a)
Length of the second piece of ribbon
= 12.15 + 2.9
= 15.05 m
Length of the first piece of ribbon
= 15.05 - 1.85
= 13.2 m
Length of the ribbon
= 12.15 + 15.05 + 13.2
= 40.4 m
(b)
Amount that Tommy paid
= 40.4 x 8
= $323.20
Answer(s): (a) 40.4 m; (b) $323.20
