An antique dealer buys an Edwardian bookshelf in England for $1700 and ships it to Australia at a cost of $250. After it is French-polished at a cost of $120, it is sold for $2500. Calculate the percentage profit on the cost price if the cost of advertising is $100 (incurred at time of sale).

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
