Arianna has a large piece of fabric that she wants to use to make some scarves. the number n of scarves she can make is inversely proportional to the area a of each scarf. if the area of each scarf is 3 square feet, then she can make 16 scarves. if the area of each scarf is 4 square feet, how many scarves can she make?
arianna can make scarves.

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)
