can I please have the solution for this question

1. Total revenue from daily ticket sales to a theme park is $1 352 400. A total of 12 000 tickets were sold and 65% of these were child's tickets with a 30% discount off the adult price. Work out the cost of an adult ticket. 3. A coat originally costing $150 is reduced by 25% in a sale and, since nobody bought the coat, a further reduction of 20% of the sale price is applied. (a) Find the final cost of the coat after both reductions. (b) Find the overall percentage reduction, and explain why this is not the same as a single reduction of 45%
