Lin has a work of art that is 14 inches by 20 inches. She wants to frame it with large paper clips laid end to end. 1. if each paper clip is 1 3/4 inch long, how many paper clips would she need?

2. How many paper clips are needed if the paper clips are spaced 1/4 inch apart.

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.
