Question:

500 tickets were sold for a concert. Of these x tickets were sold at $6 each and the remainder at $10 each. Write an expression in terms of x for the number of tickets sold at $10 each

Step-by-step explanation:

Given

x tickets costs $6 each

Others cost $10 each

Required

Write an expression for the rest

Let the remaining number of tickets be y.

Such that:

Subtract x from both sides

Hence, the number of tickets sold for $10 each is 500 - x
