First, you want to know the amount of ounces per pound. 1 pound has 16 ounces, so 2 pounds will have 32. Then, you want to take the amount of money you have and divide that by the number of ounces to get the 1 ounce cost. ( 13.98 divided by 32 = 0.4368 ) Finally, you want to multiply that 1 ounce number by 5, and you will get 2.184 or $2.18. ( or you can round up to $2.19 )
