Problema Solution
Jacki is making a couple of stools for her patio. She needs 8 wooden legs that are each yard long. She wants to cut them from redwood that is 5.25 yards long.
How much wood will remain after Jacki cuts the 8 chair legs?
Answer provided by our tutors
from 1 redwood that is 5.25 yards long Jacki can cut out 5 legs thus she will need 2 redwoods:
the total length of 2 redwoods is: 2*5.25 = 10.5 yd
the total length of 8 legs is: 8*1 = 8 yd
2*5.25 - 8 = 10.5 - 8 = 2.5 yd
2.5 yd wood will remain after Jacki cuts the 8 chair legs.
