Two companies charge these rates for printing
a brochure:
Company A charges $175 for set-up, and $0.10 per brochure.
Company B charges $250 for set-up, and $0.07 per brochure.
A linear system that models this situation is:
C = 175 + 0.10n
C = 250 + 0.7n
How many brochures must be printed for
the cost to be the same at both companies?
f + r = 391 and f - r = 141

The area of Stanley Park in Vancouver is 391 hectares. The forested area is 141 hectares more than the rest of the park.What is the area of each part of the park?
w - l = 43 and 2w + l = 107
50 wins and 7 overtime losses; exact
Write a linear system to model and solve.
In the American Hockey League, a team gets 2 points for a win and 1 point for an overtime loss. In the 2008-2009 regular season, the
Manitoba Moose had 107 points. They had 43 more wins than overtime losses. How many wins and how many overtime losses did the team have?
