Ben orders a case of his favorite macaroni and cheese. The case contains 18 same- size boxes that weigh a total of 7.2 pounds. Which set of equations represents the weight, in
pounds, of each box of macaroni and cheese, 2?
180 = 7.2
I= 0.4
7.2.0 = 18
2 = 0.4
7.23 = 18
I= 2.5
180 = 7.2
I= 2.5

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
