Withdrew 1200
spent 1/5 on travel : 1/5(1200) = 1200/5 = 240
leaving her with : 1200 - 240 = 960
spent 2/3 on hardware : 2/3(960) = 1920/3 = 640
leaving her with : 960 - 640 = 320
320 - lunch = 300.50
320 - 300.50 = lunch
19.50 = lunch <==

To determine the maximum and minimum temperatures at which nitrogen remains a liquid, use the equation |x - (-333.32)| = 12.78, where x is equal to the maximum and minimum temperatures. Using this equation, the maximum temperature is -320.54 degrees Fahrenheit while the minimum is -346.10 degrees Fahrenheit.
        
                    
             
        
        
        
Answer:
   $7
Step-by-step explanation:
Your two equations are ...
Double the second equation and subtract the first:
   2(2s +4t) -(4s +6t) = 2(42) -(70)
   2t = 14 . . . . . simplify
   t = 7 . . . . . . . divide by 2
The cost of each tie is $7.
