Answer:
51.54 mg of ibuprufen would be left after 6 hours
Step-by-step explanation:
Using exponential decay function:
y = a × [tex](1 - b)^{x}[/tex]
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 × [tex]( 1 - \frac{29}{100} )^{6}[/tex]
= 400 × [tex]( 1 - 0.29 )^{6}[/tex]
= 400 × [tex]( 0.71 )^{6}[/tex]
= 400 × 0.1281
= 51.54 mg
