Charlie bought a piece of ribbon and cut it into 3 pieces. The first piece was 1.7 m longer than the second piece. The third piece was 3.05 m shorter than the first piece.
- If the second piece was 11.95 m, find the length of the ribbon before it was cut.
- How much did Charlie pay if each metre of the ribbon was $7?
(a)
Length of the first piece of ribbon
= 11.95 + 1.7
= 13.65 m
Length of the third piece of ribbon
= 13.65 - 3.05
= 10.6 m
Length of the ribbon
= 11.95 + 13.65 + 10.6
= 36.2 m
(b)
Amount that Charlie paid
= 36.2 x 7
= $253.40
Answer(s): (a) 36.2 m; (b) $253.40
