Question

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?

Answer 1

Step-by-step explanation:

Okay, so let's represent the people as letters.

Erick= e

Tyson=t

Lane=l

They 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=90

38+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=90

To find l, we have to subtract 62 from 90.

   62+l=90

  -62    -62

--------------------

   0+l= 28

   l=28           The answer is 28.
