Matt will drive about 3,000 miles across the country on interstate 95. he plans to drive 7 hours each day averaging 60 miles per hour. what is the least number of days the trip will take?

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.
