David bought a piece of streamer and cut it into 3 pieces. The first piece was 2.1 m longer than the second piece. The third piece was 1.34 m shorter than the first piece.
- If the second piece was 13.08 m, find the length of the streamer before it was cut.
- How much did David pay if each metre of the streamer was $2?
(a)
Length of the first piece of streamer
= 13.08 + 2.1
= 15.18 m
Length of the third piece of streamer
= 15.18 - 1.34
= 13.84 m
Length of the streamer
= 13.08 + 15.18 + 13.84
= 42.1 m
(b)
Amount that David paid
= 42.1 x 2
= $84.20
Answer(s): (a) 42.1 m; (b) $84.20
