2.The perimeter of a rectangle is 78 cm. If the length is 28 cm, how wide is the rectangle?

Find the width of the rectangle.

Perimeter = 2 (W + L)

78 = 2 ( W + 28) divide both sides by 2

39 = W + 28

39 - 28 = W = 11

Let t be the number of minutes you talk C 1 and C 2 be the costs (in dollars) of the first and second plans. Find the number of talk minutes that would produce the same cost for both plans

NOTE: Round to two decimal places for your final answer.

If you talk for________________ minutes the two plans will have the same cost.

3995 + 9t = 22M

3995 = 22t - 9M

3995 = 13t

t =3995/13 ≈ 307.3 minutes will equalize the cost
