Need help with this microeconomics problem

In Gas Pump, South Dakota, there are two kinds of consumers,
Buick owners and Dodge owners. Every Buick owner has a demand func-
tion for gasoline DB (p) = 20 5p for p ≤ 4 and DB(p) = 0 if p > 4.
Every Dodge owner has a demand function Dp(p) = 15 - 3p for p ≤ 5
and Dp(p) = 0 for p > 5. (Quantities are measured in gallons per week
and price is measured in dollars.) Suppose that Gas Pump has 150 con-
sumers, 100 Buick owners, and 50 Dodge owners.
