71. First write an equation then solve it to find the answer. a)When you subtract 50 from this number and then add 15, the result is 95. This is the mystery number. b)Jim, Marilee, and Sonia bought plane tickets. Together they spent $870. Jim’s ticket cost $235, and Marilee’s ticket cost $50 more than Jim’s ticket. How much did Sonia’s ticket cost? c)All equations must do this.

73. a) m - 50 +15 = 95, m = 130 b) 235 + (235 50) + t = 870, t = $350 c) Balance!!
