1st case: 119 tickets
2nd case: 106 tickets
3rd case: 95 tickets
Step-by-step explanation:
a)
Terry and Tony want to make a profit of
P = $475
in total from the ticket sale.
Here we call the price per ticket.
Then we also call the number of tickets sold: therefore, this total profit made by Terry and Tony from the ticket sale is the product between the tickets sold, N, and the price per ticket, x:
And since they want to do a profit of P = $475, we can therefore write
b)
The equation of part a) can be re-arranged as
where N is the number of tickets sold and x the price per ticket.
The 1st group of student want to charge $4.00 per ticket, so
x = 4.00
And so the number of tickets that they should sell in this case is
The 2nd group of student want to charge $4.50 per ticket, so
x = 4.50
And so the number of tickets that they should sell in this case is
Terry and Tony want to charge $5.00 per ticket, so
x = 5.00
And so the number of tickets that they should sell in this case is

1. (2√5)/5
2. -44√7
3. 8√17
4. -6√3+12
For 1: Multiply the numerator and denominator by √5:
For 2: Simplify √112:
√112 = √(2*56) = √(2*2*28) = √(4*4*7) = 2*2√7 = 4√7
Now multiply by the -11 coefficient:
-11(4√7) = -44√7
For 3: Add the radicals as you would variables that are like terms.
For 4: Multiply by the conjugate. The conjugate of the denominator has the same values with the sign of the radical changed:
