Mark bought a piece of ribbon and cut it into 3 pieces. The third piece was 3.4 m longer than the second piece. The first piece was 3.64 m shorter than the third piece.
- If the second piece was 12.36 m, find the length of the ribbon before it was cut.
- How much did Mark pay if each metre of the ribbon was $5?
(a)
Length of the third piece of ribbon
= 12.36 + 3.4
= 15.76 m
Length of the first piece of ribbon
= 15.76 - 3.64
= 12.12 m
Length of the ribbon
= 12.36 + 15.76 + 12.12
= 40.24 m
(b)
Amount that Mark paid
= 40.24 x 5
= $201.20
Answer(s): (a) 40.24 m; (b) $201.20
