Amount earned by Sharon per item sold = $25 Base salary of Sharon per week = $100 Amount that needs to be earned by Sharon per week = $700 Let us assume the number of items sold by Sharon per week = x Then 100 + 25x = 700 25x = 700 - 100 25x = 600 x = 600/25 = 24 So Sharon needs to sell 24 items to earn a total of $700 per week. I hope you have understood the method of solving such problems.
The probability of hitting it once is the ratio of the bullseye area to the whole target. So 144/484=.2975 For it to happen twice in a row, would be this squared which is .088=.09 or 9%
