Tickets for a school concert cost $8.50 each for adults and $3.50 each for children. If 700 tickets were sold for the performance and the total raised was $4810, how many adult and children will be attending?
Let 'a' be the number of adults attending and 'c' the number of children
a) Form two equations to represent the situation
b) FInd the mnumber of adults and children attending the concert by solving the equations found in ""above simultaneously
Any help will be appreciated thanks.[/quote]
Number of adults
Number of children
(a)
Total number of people attending
.................................................. ................eqn(1)
Total money raised
.................................................. ..eqn(2)
eqn(1) and eqn(2) represent the situation.
(b)
Multiply eqn(1) by 3.50,
.................................................. ...eqn(3)
Subtract eqn(3) from eqn(2), we get
Put this value of a in eqn(1),
c = 700 - 472
c = 228
There were 472 adults and 228 children.
