in math class , jaheim and frank were working on finding the total amount of the investment after 5 years . as a final step, jaheim subtracted $150 for administrative fees from the balance he arrived at after adding in all the deposits and subtracting out the once withdrawal and brokers fee. For every semiannual statement, frank subtracted $15 from the account balance from the administrative fee. Both boys arrived at the same ending 5 year balance. how is it possible? Explain

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
