An account is opened with $7,595.96 with a rate of increase of 2% per year. After 1 year, the bank account contains $7,746.90. Assuming no deposits or withdrawals are made, which equation can be used to find y, the amount of money in the account after x years? (Round money values to the nearest penny.) y = 7,746.90(1.02)x y = 7,746.90(0.02)x y = 7,595.96(1.02)x y = 7,595.96(0.02)x

A common equation used in business is a demand equation. It expresses the relationship between the unit price of some commodity and the quantity demanded. In the equation, p represents the unit price and x represents the quantity demanded in thousands. A company sells desk lamps and has found that the demand equation for a certain style of desk lamp is given by the equation p equals negative x squared plus 23. Find the demand for the desk lamp if the price is $7 per lamp.
