Answer:The diameter will be 12 cm because the diameter is twice as long as the radius.So multiply by 2(6*2)
Number of adults' tickets (x): $7.50x + $4.00(500 - x) = $3,312.50 $7.50x + $2,000.00 - $4.00x = $3,312.50 $3.50x = $1,312.50 x = 375
No. of children's tickets (500 - x): = 500 - 375 = 125
Answer: 375 adults' tickets, 125 children's tickets
Proof (Receipts totaled $3,312.50): = (375 tickets * $7.50) + (125 tickets * $4.00) = $2,812.50 + $500.00 = $3,312.50
