Jan spends part of her year as a member of a gym. she then finds a better deal at another gym, so she cancels her membership with the first gym after x months and spends the rest of the year, y months, with the second gym. the membership to the first gym costs $75 per month, while the membership for the second gym costs $50 per month. if she ended up spending a total of $825 over the course of the year, how much time did she spend at each gym? enter a system of equations to represent the situation, then solve the system. the system of equations is . jan spent months at the first gym and months at the second gym.

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.
