(a). If the relationship between two variables p and q is given by: log4 (q + 6) = p; When p = 2; would you conclude that log q = 1? Give a reason for your conclusion by showing all your working clearly to support your answer/decision. Note: log means, logarithm to the base 10 (that is, log10) 

(b). If the demand function for a commodity is: p = 700 where p is the unit price and q is the number of units demanded. ln (q + 1) Determine how many units will be demanded at a unit price of $159.29? Note: ln means: logarithm to the base e (that is, loge ).
