The amount of bell wire in inventory is to be approximated by weight. The weight of the wire is listed in the catalog as 2 1/4 ounces per 100 feet. An empty spool of the roll weighs 1 1/4 ounces. If the roll to be inventoried weighs 20 3/8 ounces, what is the approximate amount of wire on the spool in feet?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
