Demand function (coffee)
𝑄 = 𝐷(𝑝, 𝑝𝑠, 𝑌)
𝑄 = 8. 56 − 𝑝 − 0. 3𝑝𝑠 + 0. 1𝑌)
Q = quantity demanded
p = price of coffee
ps = price of sugar
Y = income
8.56 = fixed costs of production (eg. technology, machinery)
Demand change in price
∆𝑝 = 𝑝2 − 𝑝1
Supply function (coffee)
𝑄 = 𝑆(𝑝, 𝑝𝑐, 𝑌)
𝑄 = 9. 6 + 0. 5 𝑝 − 0. 2𝑝𝑐)
Q = quantity supplied
p = price of coffee
pc = price of cocoa
9.6 = fixed costs of production (eg. technology, machinery)
Supple change in price
∆𝑄 = 𝑄2 − 𝑄1
