Two grade 11 maths problems
1.) Tickets for a concert are available at two prices. The more expensive ticket is $30 more than the cheaper one. Find the cost of each type of ticket if a group can buy 10 more of the cheaper tickets than the expensive ones for $1800.
2.) The members of a club hire a bus for $2100. Seven members withdraw from the club and the remaining members have to pay $10 more each to cover the cost. How many members originally agreed to go on the bus?
Please explain simply and show working out, THANKS! i'd like to do more of these type problems also, so if anyone out there has some, please post them! THANKS AGAIN! :):)
