Vincent bought a piece of rope and cut it into 3 pieces. The first piece was 3.2 m longer than the third piece. The second piece was 3.86 m shorter than the first piece.
- If the third piece was 13.56 m, find the length of the rope before it was cut.
- How much did Vincent pay if each metre of the rope was $10?
(a)
Length of the first piece of rope
= 13.56 + 3.2
= 16.76 m
Length of the second piece of rope
= 16.76 - 3.86
= 12.9 m
Length of the rope
= 13.56 + 16.76 + 12.9
= 43.22 m
(b)
Amount that Vincent paid
= 43.22 x 10
= $432.20
Answer(s): (a) 43.22 m; (b) $432.20
