Question

The​ seventh-grade class is raising money to have a class trip at the end of the year. They began the year with ​$1 comma 500. Now they have ​$1 comma 950 in the account. What is the percent increase for the money the class has​ raised? The class figured out that if there is a percent increase of​ 99% from the beginning of the​ year, they will have enough to pay for every student. How much money will they need to pay for every​ student?

Answer 1

Part 1:

Percent Increase = new quantity minus original quantity divided by original quantity

% increase = (1950-1500)/1500
= 450/1500
= 0.3 which is a 30% increase

Part 2:

Total money needed = original quantity multiplied by 1.99

Total = 1500(1.99)
= $2,985
