Jonas compares two wireless data plans. Which equation gives the correct value of n, the number of GB, for which Plans A and B cost the same?first answer chose is 5n = 30 + 3n, the secound is 5n = 30(4n) + 3,the third is 5n = 30 + 4n + 3, and the fourth is 5n = 30 + 3(n – 4)

(GB means “gigabytes of data.”)

Cass decided to sell game programs for the hockey game. the printing cost was over 20 cents per program with a selling price of 50 cents each. cass sold all but 50 of the programs, and made a profit of $65. how many programs were printed? letting p represent the number of programs printed, set up an equation that describes this situation. then solve your equation for p.

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
