I don't know why I got this answer wrong.

Question

Hello,

So I have been doing WebAssign homework for my math class and I have encountered this word problem:

Dave has inherited an apple orchard on which 70 trees are planted. Under these conditions, each tree yields 10 bushels of apples. According to the local WSU extension agent, each time Dave removes a tree the yield per tree will go up 0.55 bushels. Let x be the number of trees in the orchard and N the yield per tree.

(a) Find a formula for N in terms of the unknown x. (Hint: Make a table of data with one column representing various values of x and the other column the corresponding values of N. After you complete the first few rows of the table, you need to discover the pattern.)

My answer is N=(10+(70-x)0.55)x, but when I pressed submit, it was wrong. This is my fourth attempt and I don't want to get this wrong. Can someone please help me what is wrong with my answer. Thank you.

Answer 1

Tracey, I think you’ve given a correct formula for total yield, rather than yield per tree. Remove the final x to get yield per tree.
