Give an interpretation of the value of the own price elasticity calculated in question 1. 3. Using the demand equation Q-200-5P, calculate the own price elasticity when price is P-$10. Is demand elastic, unit-elastic or inelasticat price 4. Using the demand equation Q-200-5P, determine the consumer surplus (CS) when price is P-$10. What's the total expenditure (TE) when pric when price is P=$10. ALT+F10 (PC) or ALT+FN+F10 (Mac).
