Carl bought a piece of ribbon and cut it into 3 pieces. The first piece was 3.9 m longer than the third piece. The second piece was 1.71 m shorter than the first piece.
- If the third piece was 10.42 m, find the length of the ribbon before it was cut.
- How much did Carl pay if each metre of the ribbon was $2?
(a)
Length of the first piece of ribbon
= 10.42 + 3.9
= 14.32 m
Length of the second piece of ribbon
= 14.32 - 1.71
= 12.61 m
Length of the ribbon
= 10.42 + 14.32 + 12.61
= 37.35 m
(b)
Amount that Carl paid
= 37.35 x 2
= $74.70
Answer(s): (a) 37.35 m; (b) $74.70
