Oscar bought a piece of ribbon and cut it into 3 pieces. The first piece was 3.4 m longer than the second piece. The third piece was 2.21 m shorter than the first piece.
- If the second piece was 13.77 m, find the length of the ribbon before it was cut.
- How much did Oscar pay if each metre of the ribbon was $9?
(a)
Length of the first piece of ribbon
= 13.77 + 3.4
= 17.17 m
Length of the third piece of ribbon
= 17.17 - 2.21
= 14.96 m
Length of the ribbon
= 13.77 + 17.17 + 14.96
= 45.9 m
(b)
Amount that Oscar paid
= 45.9 x 9
= $413.10
Answer(s): (a) 45.9 m; (b) $413.10
