Simon bought a piece of ribbon and cut it into 3 pieces. The first piece was 3.9 m longer than the second piece. The third piece was 3.69 m shorter than the first piece.
- If the second piece was 11.43 m, find the length of the ribbon before it was cut.
- How much did Simon pay if each metre of the ribbon was $4?
(a)
Length of the first piece of ribbon
= 11.43 + 3.9
= 15.33 m
Length of the third piece of ribbon
= 15.33 - 3.69
= 11.64 m
Length of the ribbon
= 11.43 + 15.33 + 11.64
= 38.4 m
(b)
Amount that Simon paid
= 38.4 x 4
= $153.60
Answer(s): (a) 38.4 m; (b) $153.60
