Problema Solution
trevor is stringing beads to decorate his room. he wants to string at least 10 meters of beads. if each bead is 14 millimeters long. how many beads does he need ? what will the final length be?
Answer provided by our tutors
10 m = 10*100 cm = 10*100*10 mm = 10,000 mm
Let 'x' represent the number of beads.
14x > 10000 divide both sides by 14
x > 10,000/14
x > 714.28
Since the number of beads is integer follows x = 715 beads.
Trevor needs 715 beads.
The final length will be 715*14 = 10,010 mmi
