An omelette costs $1.50 more than mario's order of pancakes. after treating his family to breakfast, mario is sure that 4 omelette and 3 orders of pancakes cost more than $25 but not more than $40, including tax of 7% and a tip of $3.50. in what price range is an order of pancakes?

Why isn't my formatting working :/ So, if an order of pancakes cost x, then an omelette costs x+$1.50 ... Making the total order = 4*(x+$1.50) for omelettes + 3*x for pancakes. = 4x + $6.00 + 3x = 7x + $6.00 So, the limits: 25 = 1.07 * (7x + 6) + 3.50 40 = 1.07 * (7x + 6) + 3.50 25 = 1.07 * (7x + 6) + 3.50 x = (21.50/1.07 - 6) / 7 x = $2.01 40 = 1.07 * (7x + 6) + 3.50 x = (36.50/1.07 - 6) / 7 x = $4.01 (I rounded down in this case) Substituted back in and they work. That's how I'd do it. :/
