Answer:

50

Step-by-step explanation:

there are two methods for solving this problem

I.first we find the price for a stock by dividing their price by the number of sold  stocks

280/35=$8

to find the number of stocks that ammount to $400 we divide $400 by the price of 1 stock

400/8=50 stocks

II.we use the rule of three

35 shares of stock cost..............$280

x    shares of stock cost..............$400

to find x we multiply the elements on the diagonal and divide them by what's left

x=35*400/280=50 stock
