anonymous · Answer

here are the problems...
1.) Three sides of an equilateral triangle are increased by 20 cm, 30 cm, and 40 cm, respectively.  The perimeter of the resulting triangle is between twice and three times the perimeter of the triangle.  What can you conclude about the length of a side of the original triangle?

2.) The usual toll charge to use the Bingham tunnel is 50 cents.  If you purchase a special sticker for $5.50, the toll is only 35 cents.   At least hw many trips through the tunnel  before the sticker costs less than paying for each trip separately?
