 Mr. Fong bought a horse for $50.
 He sold the horse to Ms. Stewardson for $60.
 He missed the horse so he bought it back
from Ms. Stewardson for $70.
 Ms. Stewardson wants the horse back. She’s
offering to by it for $80. Should Mr.Fong
sell? Will he make money or lose money?

 A fair comes through Port Moody. You buy
some tickets for rides.
 You share your tickets with 2 friends so that
you each have 9 tickets.
 How many tickets did you have to begin with?
 We’ll say t represents the number of tickets
you started with. Try to create an equation.
 My equation: t = 9
3
 Brainstorm: how can we isolate t ?
 Remember that 3 = 1
3
 If we multiply both sides by 3, we’ll get:
(3) t = (9)(3)
3
 Which means t = 27. Verify the solution.
