A bicycle store costs ​$2600 per month to operate. The store pays an average of ​$60 per bike. The average selling price of each bicycle is ​$100. How many bicycles must the store sell each month to break​ even?

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)

b.-4 units

all you   do is count how many times you move
