tickets for a concert were sold for 26 in advance and 31 at the door . 44 tickets were sold in advance .how many tickets need to be sold at the door for an income of $5000

Respuesta :

= 44 * 26
= $1144 in advance

At door
= $5000 - $1144
= $3856 / $31
= 124.39

So at least 125 tickets need to be sold at the door
