Tom bought a piece of ribbon and cut it into 3 pieces. The second piece was 2.7 m longer than the first piece. The third piece was 1.88 m shorter than the second piece.
- If the first piece was 11.12 m, find the length of the ribbon before it was cut.
- How much did Tom pay if each metre of the ribbon was $10?
(a)
Length of the second piece of ribbon
= 11.12 + 2.7
= 13.82 m
Length of the third piece of ribbon
= 13.82 - 1.88
= 11.94 m
Length of the ribbon
= 11.12 + 13.82 + 11.94
= 36.88 m
(b)
Amount that Tom paid
= 36.88 x 10
= $368.80
Answer(s): (a) 36.88 m; (b) $368.80
