Part III: The number of bags of grass seed n needed to reseed a yard varies directly with the area a to
be seeded and inversely with the weight w of a bag of seed. If it takes two 3-b bags to seed an
area of 3600 ft, how many 3-1b bags will seed 11000 ft?

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.
