You take a 325 milligram dosage of ibuprofen. During each subsequent hour, the amount of medication in your bloodstream decreases by

about 29% each hour.

a) In the first blank, write an exponential decay model giving the amount of ibuprofen y (in milligrams) remaining in your bloodstream t hours

after the initial dose.

(Enter your equation without spaces, with parentheses around the b value, and using a caret for the

exponent, such as y=3(1.25)^t.)

b) In the second blank, estimate how long it takes for you to have 100 milligrams of ibuprofen in your bloodstream, rounding to the nearest

tenth: about

hours.
