Roberto deposits the same amount
of money each month into a checking
account. Use the table to write an
equation to model his balance, B,
after m months.
B = 200 + 55m
B = 200 - 55m
B = 200m + 55
B = 200m - 55

College tuition at Bedrock University has increased $500 per year for the past six years. Wilma is a freshmen this year and paid $10,250 for her tuition. She is curious about her tuition in the coming years and needs this information as motivation to graduate in four years. Assuming the tuition rate increase remains constant, write an equation to represent the tuition at Bedrock University in x years.
T = 10,250 + 500t where t is time since your freshmen year
T = 10,250 - 500t where t is time since your freshmen year
T = 10,250t + 500 where t is time since your freshmen year
T = 10,250t - 500 where t is time since your freshmen year
