Billy bought a piece of streamer and cut it into 3 pieces. The first piece was 2.9 m longer than the second piece. The third piece was 1.43 m shorter than the first piece.
- If the second piece was 10.05 m, find the length of the streamer before it was cut.
- How much did Billy pay if each metre of the streamer was $10?
(a)
Length of the first piece of streamer
= 10.05 + 2.9
= 12.95 m
Length of the third piece of streamer
= 12.95 - 1.43
= 11.52 m
Length of the streamer
= 10.05 + 12.95 + 11.52
= 34.52 m
(b)
Amount that Billy paid
= 34.52 x 10
= $345.20
Answer(s): (a) 34.52 m; (b) $345.20
