He rushed over and pulled a young lady out of the flaming truck. Farmer Brown came out gratefully thanked the traveling salesman for saving his daughter's life. Mr. Brown insisted on giving the man an award for his heroism.
So, the salesman said, "If you insist, I do not want much. Get your checkerboard and place one penny of the first square. Then place teo pennies on the next square. Then place four pennies on the third square. Continue this until all 64 squares are covered with pennies." As he'd been saving pennies for over 25 years, Mr. Brown did not consider this much an award, but soon realized he made a miscalculation on the amount of money involved.
a) How much money expressed in dollars would Mr. Brown have to put on the 32nd square?
b)How much money expressed in dollars would the traveling salesman receive in total if the checkerboard only had 32 squares?
c) Calculate the amount of money necessary to fill the whole checkerboard (64 squares). How much money expressed in dollars would the farmer need to give the salesman?

Question 58820: A designer, attempting to arrange the characters of his artwork in the form of a square grid with equal number of rows and columns, found that 24 characters were left out. When he tried to add one more row and column, he found that he was short of 25 characters. Can you find the number of characters used by the designer?
This is What I have....Let x=original number of rows of the square grid. Since number of rows and columns are equal, then number of columns is x also. So the original area, or original number of characters of the square, is x^2. Also, 24 characters were left out, so first set up the expression for total number of characters based on this. Also, when he added one more row and column, making each x+1 now, the new area is (x+1)^2 and is short 25 characters. So get a new expression for the number of characters. Set the two expressions equal since each represents the total number of characters. Solve for x.
