The average price is calculated by dividing the sum of all prices with the number of items.
average price= price1+price2+...priceN/N
In our case , we have four pairs of shoes.So, N=4.
We also know the average price. average price=$50
We also know the price of the first pair of shoes (price1), of the second (price2) and the third (price3). We need to find out Price4:
$50=$35+$40+$55+Price4/4
50*4=<span>$35+$40+$55+Price4
$200=$130+Price4
Price4=200-130
Price4=$70</span>

x = 58.33
seventy euro dollars = $ 58.33 on that particular day
