Question

Sofia bought some flats of sies. Each flat holds 9 daisies. Sofia has planted10 daisies. Is 9x 10 a reasonable way to represent the number of daisies thatSofia has left to plant? Explain your answer.

Answer 1

No. The 10 would represent how many daises she already planted while the 9 shows how many daises each flat holds. You should subtract the 10 planted daises from 9*x (x being how many flats there are) to find out how many daises Sofia has left to plant. By multiplying 9 by 10, you are not trying to find out how many daises Sofia has left to plant.

Answer 2

Explanation:

Let Sofia bought x flats of daisies.

Since each flat contains number of daisies = 9

Therefore, number of daises in x flats = 9x

If Sofia has planted 10 daisies then number of daisies left = 9x - 10

Therefore, expression shown (9x + 10) in the question is not valid to represent the number of daisies left with Sofia.

It should be (9x - 10).
