An element with mass 430 grams decays by 27.4% per minute. how much of the element is remaining after 19 minutes, to the nearest 10th of a gram?
Answers: 2
where a is the initial amount and b is the decay (or growth) rate. a is easy, 430, b though you have to make sure it is in decimal form. So for percent form (like you have) just move the decimal place to the left two times, so 27.4% becomes .274.
which shows the scenario listed. just plug in 19 for x. Another question on Mathematics
