Pierre bought a piece of ribbon and cut it into 3 pieces. The third piece was 2.9 m longer than the first piece. The second piece was 2.73 m shorter than the third piece.
- If the first piece was 12.17 m, find the length of the ribbon before it was cut.
- How much did Pierre pay if each metre of the ribbon was $10?
(a)
Length of the third piece of ribbon
= 12.17 + 2.9
= 15.07 m
Length of the second piece of ribbon
= 15.07 - 2.73
= 12.34 m
Length of the ribbon
= 12.17 + 15.07 + 12.34
= 39.58 m
(b)
Amount that Pierre paid
= 39.58 x 10
= $395.80
Answer(s): (a) 39.58 m; (b) $395.80
