An online furniture store sells chairs for $150 each and tables for $400 each. Every day, the store can ship no more than 30 pieces of furniture and must sell a minimum of $6500 worth of chairs and tables. If 10 tables were sold, determine the minimum number of chairs that the the store must sell in order to meet the requirements.

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.
