At a certain store, the price of a pair of shoes is thirty dollars more than three times the price of a pair of jeans and the price of a sweater is fifty percent more than the price of a pair of shoes. If the price of a pair of jeans is j dollars at this store, then what is the price, in dollars, of a pair of shoes, a sweater and a pair of jeans, in terms of j ?
Choose the correct option:
A) 1.5j + 10	B) 3j + 20	C) 8.5j + 75	D) 5.5j + 30	E) 8.5j + 50
Ans 8.5j + 75   Given   Price of Jeans = J   Price of shoes = 30+3J   Price of Sweater = 1.5(30+3J)   Total Price of all three items = J+30+3J+1.5(30+3J) = 75+8.5J
