An adult takes 400 mg of ibuprofen. each hour, the amount of ibuprofen in the persons system decreases by about 29%. how much ibuprofen is left after 6 hours

51.54 mg of ibuprufen would be left after 6 hours

Step-by-step explanation:

Using exponential decay function:

y = a ×

y : Final amount after decay

a : Original amount = 400

x : time = 6 hrs

1 - b: decay factor = 29%

Amount of Ibuprofen left after 6 hours will be:

= 400 ×

= 400  ×

= 400  ×

= 400  × 0.1281 

= 51.54 mg

95.03 is the answer. hope this !
