A desalinization process is eliminating 20% of the salt from seawater every 10 minutes. There are initially 350 g of salt in 10 liters of water. Find an exponential function for A, the grams of
salt in the 10 liters of seawater t minutes after the process has begun. (See Example 5 in this section.)
A=
Use the model to predict the amount of salt (in grams) in the seawater after 55 minutes. Round to the nearest whole number.
