Let number of children's ticket at ₦250.00 each = x ∴ Number of adult tickets at ₦520.00 each = 5x Then, Total amount of money received from children's tickets = 250x Total amount of money received from adult tickets = 520(5x) ⇒ 250x + 520(5x) = 171,000 ⇒ 250x + 2600x = 171,000 ⇒ 2850x = 171,000
⇒ x=171,0002850=60 ∴ 60 tickets were sold at ₦250.00 and 300 tickets were sold at ₦520.00
