Eric bought a piece of rope and cut it into 3 pieces. The first piece was 3.3 m longer than the third piece. The second piece was 1.14 m shorter than the first piece.
- If the third piece was 11.98 m, find the length of the rope before it was cut.
- How much did Eric pay if each metre of the rope was $7?
(a)
Length of the first piece of rope
= 11.98 + 3.3
= 15.28 m
Length of the second piece of rope
= 15.28 - 1.14
= 14.14 m
Length of the rope
= 11.98 + 15.28 + 14.14
= 41.4 m
(b)
Amount that Eric paid
= 41.4 x 7
= $289.80
Answer(s): (a) 41.4 m; (b) $289.80
