2006 attendance: 45 205; 2008 attendance: 45 325
Create a linear model and solve.
The mean attendance at the Winnipeg Folk Festival for 2006 and 2008 was 45 265. The attendance in 2008 was 120 more than the attendance in 2006.What was the attendance in each year?
t + s = 545 and t - s = 185
Talise's dress: 365 cones; her sister's dress: 180 cones
Create a linear model and solve.
Talise folded 545 metal lids to make cones for jingle dresses for herself and her younger sister. Her dress had 185 more cones than her sister's dress. How many cones are on each dress?
10k + 20b = 200 and 15k + 25b = 270
1 knife: 8 beaver pelts; 1 blanket: 6 beaver pelts
Create a linear model and solve.
Years ago, people bought goods with beaver pelts instead of cash. Two fur traders purchased some knives and blankets from the Hudson's Bay Company store at Fort Langley, B.C. The items and the cost in beaver pelts for each fur
trader are shown below:
10 knives + 20 blankets = 200 beaver pelts
15 knives + 25 blankets = 270 beaver pelts
What is the cost, in beaver pelts, of one knife
and of one blanket?
