The other answer here, by Nicholasrichar, has the correct answers,
but it's a pain to follow through step-by-step because of the formatting
problem. Here's my solution, leading to the same answers:
P = cost of pancakes
cost of omeletto, = P+1.50
4 omelettes = 4P + 6
3 pancakes = 3P
Total cost of food = 7P + 6
After 7% tax = 1.07(7P + 6)
After tip = 1.07(7P + 6) + 3.50
Eliminate parentheses: 1.07(7P) + 1.07(6) + 3.50 =
7.49P + 6.42 + 3.50 =
Total cost of breakfast: 7.49P + 9.92 .
Having a "range" between $25 and $40 is really two inequalities:
First inequality: $25 < 7.49P + 9.92
Subtract 9.92 from each side: 15.08 < 7.49P
Divide each side by 7.49: $2.013 < P
An order of pancakes costs more than $2.01 .
Second inequality: 7.49P + 9.92 < $40
Subtract 9.92 from each side: 7.49P < 30.08
Divide each side by 7.49 : P < $4.016
An order of pancakes costs less than $4.02.
The price range of an order of pancakes is $2.01 < Pancakes < $4.02 .
