Answer:5
Step-by-step explanation:
Form the equation 27.75n+5.50=144.25
Subtract 5.50 from 144.25.
144.25-5.50=138.75. Now you have 27.75n=138.75. Divide 138.75 by 27.75, 138.75/27.75=5. So n=5
Sammy bought 5 tickets.
To find this answer, first subtract 5.50 from 144.25, since that amount was for the overall order, and not each individual ticket. $144.25 - $5.50 = $138.75
Now, to find the number of tickets she bought, divide $138.75 by $27.75. $138.75 ÷ $27.75 = 5. Thus meaning she bought 5 tickets.
I hope this helps!
