Answer:The equation that will represent the number of grams present after n hours is

3.035 grams will be left one day from now.

Step-by-step explanation:Exponential equation for the amount of a substance:The exponential equation for the amount of a substance is given by:

In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.

A radioactive isotope is decaying at a rate of 15% every hour.This means that

Currently there are 150 grams of the substance.This means that

Write an equation that will represent the number of grams present after n hours.How much will be left one day from now?One day is 24 hours, so this is A(24).

3.035 grams will be left one day from now.
