The least number of customers in a shop at any time during the day was 15. fran represents this situation with the inequality c > 15, where c is the number of customers in the shop. is fran correct? explain

the answer to your question is b.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
