500 tickets must be sold. 54 students have sold nine tickets each. How many tickets are left to be sold?

[equation]

14 tickets. Equation form : 500 - 486=x.

Step-by-step explanation:

Variables are always the unknown. What you don't know from the given information is the number of tickets left to be sold. 54*9=486. So x is equivalent to 500-486 aka 14

500 - (54 x 9) = x

x = 14

Step-by-step explanation:

if 54 students have sold nine tickets each, that would equal 486 tickets sold. 500 tickets minus 486 equals 14 tickets.
