9. The seventh-grade class is raising money to have a class trip at the end of the year. They
began the year with $1,500. Now they have
$1,650 in the account.
a. What is the percent of increase for the
money the class has raised?
b. Make Sense and Persevere The class
figured out that if the percent increase is
99% from the beginning of the year, the
class will have enough money for every
student to go on the field trip. How
much money will the class need to raise
for every student to go.
