A diamond ring sold for $3,132 including tax. If the tax rate where the diamond was purchased is 7.4% find the price of the ring before the tax was added Round to the nearest cent as necessary.

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
