plz help Erick, Tyson, and Lane together sold 90 tickets for the school banquet. Erick sold 38 tickets, and Tyson sold 24 tickets. How many tickets did Lane sell?

Step-by-step explanation:Okay, so let's represent the people as letters. Erick= eTyson=tLane=lThey sold 90 tickets for the school banquet altogether. This means that e+t+l equals 90. Now since you know how much Erick and Tyson sold, this would mean you can replace your letters (variables) with numbers in your equation, like so:e+t+l=9038+24+l=90 (l remains a letter because we don't know how many he sold.)Now add 38 and 24 to get 62. 62+l=90To find l, we have to subtract 62 from 90.    62+l=90   -62    -62--------------------    0+l= 28    l=28           The answer is 28.
