Ms. Hanley and Ms. Simpson's classes are trying to see which class can raise the most money for their end of year party.
• Ms. Hanley's class has already raised $150 dollars and each student is going to
donate $4 more dollars.
Ms. Simpson's class has already raised $100 dollars and each student is going to
donate $9 more dollars.
Which equation can be used to find t, the number students needed to donate for
each class so that the total amount raised is the same for both classes?
A. 9t + 150 = 4t + 100
B. 4t + 150 = 9t + 100
C. 9 + 150t = 4 + 100t
D. 4 + 150t = 9 + 100t
