The drama club sold $779 worth of tickets to the school play. Student tickets cost $3 a piece and tickets for everyone else cost

svetlana [45]

Answer:

The equation will be: $3s+5t=779$

Step-by-step explanation:

The number of student tickets that were sold $=s$

and the number of other tickets that were sold $=t$

Student tickets cost $3 a piece and tickets for everyone else cost $5 each.

So, the total cost of $s$ student tickets $=\$3s$ and the total cost of $t$ other tickets $=\$5t$

Given that, the drama club sold total $779 worth of tickets.

So, the equation will be: $3s+5t=779$
