given that market demand curve is P(Q)= 815-2Q , market supply curve p(Qs)=10+0.5Qs. In a market equilibrium, Q=322, P= 171, and a price ceiling of $85.50 find the excess demand. i think the answer is 128.25 units but I'm not sure

If the demand equation of a product is p= 210-g and the supply equation for a product is p= 29+2 then, the equilibrium price equals

In the market for hand sanitizers the demand function is given by: q = 80 - p, where q is the quantity of hand sanitizers (in thousands) and p is the price of hand sanitizers in dollars. Suppose the current market price for hand sanitizers is $4. 1. What is the inverse demand function equal to? Draw it in a diagram. 2. At a price of $4, what is the level of consumer surplus? 3. Due to the unprecedented COVID-19 pandemic, people's preferences for sanitizing their hands change in favor of hand sanitizers. In fact, for any given price of hand sanitizers, people now want to purchase 20 units (in thousands) more hand sanitizers. o What is the new demand curve? o What is the new inverse demand curve? o Draw the new inverse demand curve in your diagram. 4. Suppose that after the increase in demand, the new price becomes $8. What is consumer surplus equal to at this new price (and with the new inverse demand curve)? 5. [Challenge Question] What would the consumer surplus be if the government…

Demand conditions in the market change. So, now the equation system describing (in inverse form) demand and supply in this competitive market is: p = 52 - 0.5 q, p = 2 + 0.1 q. Determine this market's equilibrium quantity q* (in units of the commodity).
