Seth bought a piece of ribbon and cut it into 3 pieces. The third piece was 3.3 m longer than the second piece. The first piece was 2.51 m shorter than the third piece.
- If the second piece was 12.07 m, find the length of the ribbon before it was cut.
- How much did Seth pay if each metre of the ribbon was $4?
(a)
Length of the third piece of ribbon
= 12.07 + 3.3
= 15.37 m
Length of the first piece of ribbon
= 15.37 - 2.51
= 12.86 m
Length of the ribbon
= 12.07 + 15.37 + 12.86
= 40.3 m
(b)
Amount that Seth paid
= 40.3 x 4
= $161.20
Answer(s): (a) 40.3 m; (b) $161.20
