Well,
Since the denominators are the same, we can add.
B because it’s a random sample and it’s not biased
A. fixed costs of 18,000 and then 40 per canoe
c(x) = 18000 +40x
B) sell price is 160 per canoe, so r(x) = 160x
C) break even, set both a and b equal to each other and solve for x
18000 + 40x = 160x
subtract 40x from each side:
1800 = 120x
divide both sides by 120
x = 18000 / 120 = 150 canoes
break even means the money coming in equals the money going out
