PLZ HELP MEH IN A TESTT A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be described as y = two fifthsx − 4. What should the equation of the new route be if it is to be perpendicular to the old route and will go through point (P, Q)?

y − Q = negative five halves(x − P)
y − Q = two fifths(x − P)
y − P = negative five halvesx − Q)
y − P = two fifths(x − Q)

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
