Explanation

Question 7:The fastest way to answer this question is to assign numerical values to the percentages given in the graphs. You can choose any numbers to work with and get the same answer, but since the graphs give percentages, choosing 100 total plants sold will make things easy. If total plants sold were 100, 71 were annuals. Of those 71 annuals, the second graph says that 24% were herbs. 24% × 71 = 17.04. Since you started with 100 total plants, 17.04/100 = 17.04%. Choice D is nearest 17.04%, so it is the best answer.

Question 8: 1,000 plants were sold, and from the first graph, you know that 71% of them, or 710, were annuals. Looking at the second graph, 40% of the 710 annuals, or 284, were tomatoes. Of those, any, all or none could have been Beefsteaks—you don’t know anything about that. So any number between 0 and 284 will work, making choices A, B, and C the correct answer.

Hey,

I think you are right.

Question 7 Should be E not D. The official answer is D though.
